Web1) Random movement. sometimes phospholipids acquire enough energy to just move. This depends entirely on factors like temperature, whether there's cholesterol nearby, and whether the phospholipid has saturated or unsaturated tails. 2) Proteins can either actively or passively catalyze movement of a phospholipid across the membrane. WebPhosphatidylethanolamine. Biosynthesis of various phospholipids (including phosphatidylethanolamine) in bacteria. Phosphatidylethanolamine ( PE) is a class of phospholipids found in biological membranes. [1] They are synthesized by the addition of cytidine diphosphate - ethanolamine to diglycerides, releasing cytidine monophosphate.
