WebSep 26, 2024 · Sphingolipids are mainly found in membranes of cells, where the hydrophobic tail of phospholipids and other membrane lipids such as cholesterol are embedded. Both plasma and organelle membranes contain sphingomyelin, which distributes symmetrically throughout the membrane’s bilayer. WebLipids discussed in detail in this study are triglycerides and their derivatives, fatty acids and their derivatives, natural plant and animal waxes, and phospholipids. Also mentioned are sphingolipids, carotenoids, tocopherols and other types of lipids. 2. LIPID FUNCTIONS Lipids possess important functions at very different facets.
