WebQuestion: Glycerophospholipids (phosphoglycerides) are components of cell membranes. They are composed of a glycerol molecule with two fatty acids attached to the first and second carbon atoms, and a polar (hydrophilic) group attached through a phosphodiester linkage to the third carbon atom. Each of the given molecules is a glycerophospholipid. WebThe four main groups of lipids include: 1. Fatty acids (saturated and unsaturated) 2. Glycerides (glycerol-containing lipids) 3. Nonglyceride lipids (sphingolipids, steroids, waxes) 4. Complex lipids (lipoproteins, glycolipids) Lipids can also be broadly subdivided as either saponifiable or nonsaponifiable. Fatty Acids
