The cell membrane consists of a lipid bilayer, made up of two layers of phospholipids with cholesterols (a lipid Instead, oligosaccharides are found bound, for example, to sphingolipids (making cerebrosides or gangliosides) or proteins (making glycoproteins). Vitamin C is an essential water-soluble vitamin that must be obtained from dietary sources as it cannot be produced by the body. Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. Sphingolipids are based on ceramide and either have a phosphocholine head group or carbohydrate structure. ISSFAL, the International Society for the Study of Fatty Acids and Lipids is an International Scientific Society established in 1991, with more than 500 members from over 40 countries.
