Dipalmitin (CAS 26657-95-4)

Dipalmitin, or 1,2-dipalmitoyl-sn-glycerol, is a specific type of diacylglycerol primarily consisting of two palmitic acid molecules esterified to the first and second carbon atoms of a glycerol backbone, with the third carbon typically free or linked to a hydroxyl group. This structured lipid is commonly used in research focused on fat metabolism and the physical chemistry of lipids. Dipalmitin plays a crucial role in studies that explore the melting and crystallization behaviors of saturated fats, providing insights into the solidification processes relevant to food science, particularly in the production and stabilization of fats in processed foods. Its clearly defined melting point and crystalline structure make dipalmitin an ideal model compound for thermodynamic and kinetic studies in lipid research. Additionally, dipalmitin is utilized in the formulation of model lipid systems for studying lipid interactions and behavior in simulated biological membranes. These activities help in understanding the mechanics of lipid bilayers and the role of specific lipid types in membrane structure and dynamics. Beyond biological mimicry, dipalmitin′s properties are also explored in materials science for developing lipid-based coatings and in energy storage systems where phase change materials play a critical role.
