Phospholipid head function

WebNov 8, 2024 · Lipid headgroups are substituents that attach to the glycerol, sphingosine, or cholesterol backbones of polar membrane lipids. Phospho- and glycolipids have headgroups linked to the backbone through a phosphodiester bond (Figure 1.2. 2 ). Understanding head group behavior is necessary for the study of membrane biology. WebAug 14, 2024 · Phospholipids, also known as phosphatides, are a class of lipids whose molecule has a hydrophilic “head” containing a phosphate group, and two hydrophobic “tails” derived from fatty acids, joined by a glycerol molecule.
