Where does the synthesis of phospholipids occur?

The synthesis of phospholipids occurs in the smooth endoplasmic reticulum (SER), which is a type of endoplasmic reticulum that lacks ribosomes on its surface. The SER is involved in various metabolic processes, including the synthesis of lipids, phospholipids, and steroids. Phospholipids are a type of lipid that are important structural components of cell membranes. They are synthesized in the SER and then transported to the Golgi apparatus for further modification and sorting before being incorporated into the cell membrane.
