Phospholipids are the major structural components of biological membranes in plants, animals, and yeasts. In plants, phospholipids predominate extra-chloroplast membranes including the plasma membrane, mitochondria membrane, endoplasmic reticulum, and microsomal membrane, with phosphatidylcholine and phosphatidylethanolamine being the major constituents. Phospholipids are mostly synthesized in the endoplasmic reticulum membrane. Once synthesized, they are transported to other phospholipid containing membranes.

At least three different pathways contribute to the biosynthesis of an L-1-phosphatidylethanolamine in plants: The decarboxylation pathway (phosphatidylethanolamine biosynthesis I), the phosphoryl-ethanolamine transfer pathway (phosphatidylethanolamine biosynthesis II), and the base (head group) exchange pathway (phosphatidylethanolamine biosynthesis III). The phosphoethanolamine transfer pathway (this one) is believed to be the major pathway in plants.
