Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. 87-13-8, formula is C10H16O5, Name is Diethyl 2-(ethoxymethylene)malonate. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Reference of 87-13-8.
Ribeiro, Tania Braganca;Costa, Celia Maria;Bonifacio- Lopes, Teresa;Silva, Sara;Veiga, Mariana;Monforte, Ana Rita;Nunes, Joao;Vicente, Antonio A.;Pintado, Manuela research published 《 Prebiotic effects of olive pomace powders in the gut: In vitro evaluation of the inhibition of adhesion of pathogens, prebiotic and antioxidant effects》, the research content is summarized as follows. Olive pomace is a biowaste rich in polyphenols and insoluble dietary fiber with high potential to develop new value chains towards a sustainable and circular bioeconomy. Regarding gut health, olive pomace phenolics and insoluble dietary fiber (after possible fermentation) could act as antioxidants, antimicrobial and prebiotic agents. These potential beneficial effects on the gut were analyzed for two powders from olive pomace: liquid-enriched powder (LOPP) – mostly source of phenolics – and pulp-enriched powder (POPP) – main source of insoluble dietary fiber. LOPP and POPP were subjected to an in vitro simulated gastrointestinal digestion followed by in vitro faecal fermentation The undigested fraction retained in the colon was analyzed regarding its potential antioxidant, antimicrobial and prebiotic effects. LOPP and POPP did not impact the gut microbiota diversity neg., showing a similar ratio of Firmicutes/Bacteroidetes compared to a pos. control (FOS). LOPP exhibit a pos. (similar to FOS) effect on the Prevotella spp./Bacteroides spp. ratio. Both powders promoted more the production of short-chain fatty acids (mainly acetate > butyrate > propionate) than FOS and showed also significant total phenolic content and oxygen radical absorbance capacity during faecal fermentation until 48 h. Besides that, these powders showed mucin-adhesion inhibition ability against pathogens, principally POPP against Bacillus cereus (22.03 ± 2.45%) and Listeria monocytogenes (20.01 ± 1.93%). This study demonstrates that olive pomace powders have prebiotic effects on microbiota, including the stimulation of short-chain fatty acids production, potential antioxidant and antimicrobial activity which could improve the human gut health.
Reference of 87-13-8, Diethyl ethoxymethylenemalonate is a useful research compound. Its molecular formula is C10H16O5 and its molecular weight is 216.23 g/mol. The purity is usually 95%.
Diethyl ethoxymethylidenemalonate is a matrix effect reagent used in analytical chemistry. It is often used as a substrate for the cycloaddition process, which produces malondialdehyde and hydrochloric acid. The UV-absorption of the malondialdehyde can be measured to determine the concentration of the sample. Diethyl ethoxymethylidenemalonate is also used as a dna template in binding constants, where it binds with amines to form complexes that are then analyzed by light emission. It has been shown to have an inhibitory effect on gyrase and trifluoroacetic acid, both enzymes involved in DNA replication., 87-13-8.
