WebFatty acid-glycerol linkages. Typically, the fatty acids are esterified to the glycerol at carbon position C-1 and C-2. The glycerol backbone is chiral and this reflects the sn-1 and sn-2 positions respectively. However, there are other variants of linkage chemistry. It is possible to have ether and vinyl-ether linkages of lipids. WebNov 8, 2024 · Phosphatidylethanolamine (PE) is the second most abundant phospholipid and is comprised of the typical phosphatidic acid with an additional head group component, namely ethanolamine. Ethanolamine is both a primary amine and alcohol, and attaches to the PA head group via the hydroxyl.
