Biological molecules (Iv): Lipids Lipids are a class of nonpolar molecules that include the fats cholesterol, fatty acids, lipid-soluble vitamins, waxes, soaps, glycerophospholipids, sphingolipids, and others. Lipids are found in the membranes of cells, the endoplasmic reticulum and in specialized fat storage cells called adipocytes. Example of lipids Fat (Triacylglycerols ): Fats are composed of glycerol esterified to three fatty acids. Fats are derived from three primary sources:(1)the diet;(2)de novo biosynthesis, particularly in liver; and (3) storage depots in adipocytes
