Lignin of high purity and structural integrity was isolated from the enzymic residue of corn stover. Degradation of the lignin by laccase, lignin peroxidase, and manganese peroxidase was investigated. Structural changes in the lignin after degradation were characterized by SEM, nitrogen adsorption and Fourier transform IR spectroscopy, and the enzymic products were systematically analyzed by gas chromatog. mass spectrometry. The highest percentage of lignin degradation was obtained with a mixture of three enzymes (25.79%): laccase (Lac), the starting enzyme of the mixed enzyme reaction, worked with lignin peroxidase (LiP), and manganese peroxidase (MnP) to further degrade lignin. This degradation destroyed the macromol. structure of lignin, broke its key chem. bonds, and opened benzene rings, thus producing more acidic compounds This study elucidated the concept of degrading lignin from corn stover using the Lac, LiP and MnP enzymes synergistically, thus providing a theor. basis for the biodegradation of lignin. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Product Details of 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Product Details of 31566-31-1

Preparation and in-vitro evaluation of 0.05% 5-fluorouracil solid lipid nanoparticle gel in the treatment of actinic keratosis was written by Aswathy, B.;Ravindran, Remya;Ramkumar, R. P.;Apaduvanpadavath, Labeeb. And the article was included in International Journal of Pharmaceutical Sciences and Research in 2022.Synthetic Route of C21H44O5 The following contents are mentioned in the article:

The present study focused on the formulation and in-vitro evaluation of 0.05% 5-fluorouracil solid lipid nanoparticle gel in treating actinic keratosis. The in-vitro release profile of solid lipid nanoparticle gel is higher than the marketed cream formulation; thus, we can reduce the dose of formulation by this method. This is prepared using tween 80, tween 20, glycerol monostearate, glycerol, and lecithin. Pre-formulation studies for the pure drug were conducted, and formulations were evaluated based on viscosity, encapsulation efficiency and in-vitro drug release study using franz diffusion cell. FTIR study of pure drug-polymer and formulation proves there is no chem. interaction between them. Formulation SLN2 had appropriate viscosity of 1738.34, the highest encapsulation efficiency of 94.45%, drug loading 31.97%. SLN2 shows 95% cell viability. The in-vitro release study was found to have a zero-order release profile. Compared to all other formulations, this indicates the predominant mechanism of drug release is diffusion. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Synthetic Route of C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water.

Development and characterization of novel bigels based on monoglyceride-beeswax oleogel and high acyl gellan gum hydrogel for lycopene delivery was written by Zhu, Qiaomei;Gao, Jianbiao;Han, Lijun;Han, Kexin;Wei, Wei;Wu, Tao;Li, Jinlong;Zhang, Min. And the article was included in Food Chemistry in 2021.Formula: C21H44O5 The following contents are mentioned in the article:

The aim of present study was to develop novel bigels as a semi-solid vehicle for lycopene delivery. Bigels were prepared by using the mixture of glycerol monostearate (GMS)-beeswax based oleogel and high acyl gellan gum hydrogel in different proportions. The confocal microscopic observations showed that the obtained bigels were oleogel-in-hydrogel, and droplets became larger with increased contents of oleogel. Higher fractions of oleogel increased the mech. strength (storage modulus, firmness) of bigels. According to the rheol. results, all bigels exhibited solid-like characteristics since the storage modulus were larger than loss modulus. DSC results showed that the melting temperature of bigel was higher than that of oleogel. During in vitro simulated gastrointestinal digestion, the total release percentages varied from 60% to 80%, and a higher content of oleogel within bigels could slower down the release of lycopene, suggesting that a higher proportion of oleogel was beneficial for delivery of fat-soluble nutraceuticals. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Formula: C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Formula: C21H44O5

Monoglyceride oleogels for lipophilic bioactive delivery – Influence of self-assembled structures on stability and in vitro bioaccessibility of astaxanthin was written by Wang, Shujie;Chen, Kefei;Liu, Guoqin. And the article was included in Food Chemistry in 2022.HPLC of Formula: 31566-31-1 The following contents are mentioned in the article:

The present study investigated the influence of self-assembled structures on stability and in vitro bioaccessibility of astaxanthin by modifying the structures with different processing conditions. The self-assembled structures of GMS oleogels were changed to produce smaller crystals and more compact network at higher glycerol monostearate (GMS) concentration and lower cooling temperature, resulting in higher hardness, oil binding capacity, and viscoelastic properties of oleogels. In the stability test, the highest retention ratio of astaxanthin was observed in oleogels formed at 4°C and 10% GMS, indicating that the denser network structures were more effective to prevent the degradation of astaxanthin. During in vitro digestion, the self-assembled structures of oleogels and the nature of GMS mols. affected the lipolysis and micellization, which in turn regulated the bioaccessibility of astaxanthin. Collectively, GMS oleogels were effective delivery materials for improving the stability and bioaccessibility of lipophilic bioactives. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1HPLC of Formula: 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 31566-31-1

Acquired resistance to vemurafenib (PLX4032) is a thorny issue in BRAF^V600E mutant melanoma therapy. Ferroptotic programmed cell death is a potential strategy for combating therapy-resistant cancers. This study uncovers the adaptation and abnormal upregulation of PUFAs and bioactive oxylipin metabolism in PLX4032 resistant melanoma cells. Phyto-sesquiterpene lactone, DET, and its derivative, DETD-35, induced lipid ROS accumulation and triggered ferroptotic cell death in PLX4032 sensitive (A375) and resistant (A375-R) BRAF^V600E melanoma cells by reprogramming glutathione and primary metabolisms, lipid/oxylipin metabolism, and causing mitochondrial damage in which DETD-35 showed superior efficiency to DET. Author discovered that DET and DETD-35 are a new type of GPX4 enzyme inhibitor through non-covalent binding. This study provides new insight into the therapeutic mechanisms of both DET and DETD-35 to combat PLX4032 sensitive/resistant BRAF^V600E mutant melanomas via targeting GPX4 and ferroptosis.

Accelerated Non-Enzymatic Fatty Acid Esterification during Microdroplet Collision: A Method for Enhanced Sustainability was written by Basuri, Pallab;Kumar, Jenifer Shantha;Das, Subhashree;Pradeep, Thalappil. And the article was included in ACS Sustainable Chemistry & Engineering in 2022.Application In Synthesis of Glyceryl monostearate The following contents are mentioned in the article:

Accelerated non-enzymic and metal-free “reaction and extraction” of sugar esters at the interface of two immiscible liquid microdroplets is demonstrated. The bimol. reaction occurs by collision of microdroplets originating from two home-built electrospray sonic ion sources, carrying sugar mols. in water and long-chain fatty acids in toluene, resp. Our method shows that the rate of reaction is enhanced ~10⁷ times in comparison to the bulk, initiated by ultrasonic activation. Such a high rate of reaction in the microdroplets can be attributed to factors such as surface activity, concentration enhancement, partial solvation, and temperature-assisted dehydration of the species occurring in microdroplets. We provide evidence for an interfacial nucleophilic addition-elimination reaction mechanism. This method of synthesis is extended to 18 similar reactions. Microdroplet synthesis offers a sustainable method for biphasic reactions, eliminating the need for phase transfer reagents and activating agents such as acids/bases, metals, or enzymes.

And the article was included in Journal of Food Engineering in 2023.Related Products of 31566-31-1 The following contents are mentioned in the article:

This paper reports the successful development of low-fat chocolate spreads using water-in-oleogel emulsions. Glycerol monostearate (20% wt) was incorporated into corn oil to fabricate the oleogel phase and then water was mixed with oleogel at weight ratios of 0:100, 45:55, 50:50, and 55:45 (water: oleogel) to produce water-in-oleogel emulsions. The chocolate spreads prepared with water-in-oleogel emulsions were analyzed and compared in terms of phys., rheol., and sensory characteristics. It was found that the emulsion made at 45:55 water: oleogel ratio (45% replacement of oleogel with water), resulted in chocolate with quite similar microstructural integrity, water activity, Casson viscosity, yield stress, linear viscoelastic region, firmness, and spreadability to the reference sample (100% of oleogel). Moreover, the reduced-fat chocolate spread displayed comparable (if not superior) sensory scores and acceptability to the full-fat sample. In conclusion, water-in-oleogel emulsion displayed the potential for use in the formulation of reduced-fat chocolate spread.

The search for novel strategies to formulate bioactive mols. for topical administration is a matter of permanent interest in the pharmaceutical field. As a contribution, the present work deepens the bigels, i.e., matrix-in-matrix systems resulting from mixing a hydrogel and an organogel. Hypromellose, collagen, gelatin, alginate, sesame oil, medium-chain triglycerides, and iso-Pr myristate were included among the starting materials investigated. Nonetheless, the bigels’ homogeneity and stability are determined by the nature and proportion of the starting materials and operating conditions used during their preparation On the other hand, bigels exhibit a different structure than the starting gels and other related systems such as emulgels, which govern their rheol. and texture behaviors, and modulate the drug delivery, as evidenced through the tests using diclofenac in its dissociated and non-dissociated forms. On this basis, this semisolid system attracts attention to developing versatile pharmaceutical products wherein controlled release of active mols. is intended.

Solid lipid nanoparticles for phytosterols delivery: The acyl chain number of the glyceride matrix affects the arrangement, stability, and release was written by Guo, Shu-Jing;Ma, Chuan-Guo;Hu, Yu-Yuan;Bai, Ge;Song, Zhen-Jia;Cao, Xin-Qi. And the article was included in Food Chemistry in 2022.Quality Control of Glyceryl monostearate The following contents are mentioned in the article:

The lipid matrix plays a key role in solid lipid nanoparticles (SLNs) embedding active ingredients. To investigate the influence of lipid matrix structure on arrangement, release, and stability of solid lipid nanoparticles, three phytosterols formulations with different carrier glycerides [glycerol monostearate (GMS), glycerol distearate (GDS), and glycerol tristearate (GTS)] were prepared and evaluated. X-ray diffraction and differential scanning calorimetry revealed the lowest crystallinity of phytosterols in the GMS matrix, corresponding to the maximum bioaccessibility (40.2%) in vitro experiments Sustained release and better stability were observed from GDS and GTS matrixes, which could be attributed to strong mol. interactions or a core-rich structure inside the nanoparticles. Mol. dynamics simulations demonstrated that the affinity between phytosterols and glycerides decreased in the order GDS > GTS > GMS, as well as explaining the release and storage capacities of the three nanoparticles. This study would facilitate the rational design of SLNs in functional foods.

Comparative Metabolite Fingerprinting of Four Different Cinnamon Species Analyzed via UPLC-MS and GC-MS and Chemometric Tools was written by Farag, Mohamed A.;Kabbash, Eman M.;Mediani, Ahmed;Doll, Stefanie;Esatbeyoglu, Tuba;Afifi, Sherif M.. And the article was included in Molecules in 2022.Related Products of 31566-31-1 The following contents are mentioned in the article:

The present study aimed to assess metabolites heterogeneity among four major Cinnamomum species, including true cinnamon (Cinnamomum verum) and less explored species (C. cassia, C. iners, and C. tamala). UPLC-MS led to the annotation of 74 secondary metabolites belonging to different classes, including phenolic acids, tannins, flavonoids, and lignans. A new proanthocyanidin was identified for the first time in C. tamala, along with several glycosylated flavonoid and dicarboxylic fatty acids reported for the first time in cinnamon. Multivariate data analyses revealed, for cinnamates, an abundance in C. verum vs. procyandins, dihydro-coumaroylglycosides, and coumarin in C. cassia. A total of 51 primary metabolites were detected using GC-MS anal. encompassing different classes, viz. sugars, fatty acids, and sugar alcs., with true cinnamon from Malaysia suggested as a good sugar source for diabetic patients. Glycerol in C. tamala, erythritol in C. iners, and glucose and fructose in C. verum from Malaysia were major metabolites contributing to the discrimination among species.

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Related Products of 31566-31-1
