The current research explores the involvement of head group size, chem. group type, and aliphatic tail in the mol. self-assembly of various oil structuring agents with similar 18-carbon aliphatic chains and hydroxyl, carbonyl, and/or carboxyl groups, in canola oil. Thermal and mech. analyses at different molar concentrations emphasized the involvement of van der Waals (vdW) interactions and hydrogen bonds (H-bonds) in the self-assembly process. Higher contribution of vdW-forces in the self-assembly was observed when increasing mol. concentration from medium to high. The presence of H-bonds corresponding with organized crystal structures was detected in samples containing hydroxyl or carboxyl groups using nano-structure anal. Absence of such groups led to ordered organization only at high concentrations, implying the involvement of vdW interactions. Polarized images demonstrated curved structures for long head group mols., implying the formation of intermol. H-bonds with neighboring mols. leading to structure curvature. The current results provide exptl. indication to involvement of different forces, i.e. H-bonds and vdW, in the mol. self-assembly of oil structuring agents in oil which can be further exploit while developing new oleogel system based on low mol. weight gelators. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Related Products of 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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
