1,2-Distearoyl-3-palmitoyl-rac-glycerol (CAS 5281-50-5)

1,2-Distearoyl-3-palmitoyl-rac-glycerol is a triglyceride molecule distinguished by its specific fatty acid composition, where two molecules of stearic acid are esterified to the first and second hydroxyl groups of glycerol, and one molecule of palmitic acid is attached to the third. This arrangement of fatty acids, all of which are saturated, makes it an ideal subject for research in lipid science, particularly in the study of the physical properties of saturated fat systems. The uniform saturation across its fatty acid chains allows for the investigation of the melting behavior, crystallinity, and thermal properties of lipid compounds under controlled conditions. In research settings, this molecule serves as a model to assess the impact of chain length and saturation on the stability and behavior of lipid bilayers and other lipid-based structures. Its use in non-biological studies includes the examination of lipid interactions in food science, where understanding lipid behavior can influence the texture and stability of food products. Additionally, it has been utilized in material science to explore the formation and properties of lipid-based films and coatings, providing insights into the development of lipid-containing materials with specific mechanical properties. The molecule′s ability to organize into distinct phases and structures also supports studies on the thermodynamics of lipid systems, contributing valuable data to theoretical models of lipid behavior.
