Description of Phosphatidylethanolamine:
Phosphatidylethanolamine (PE) is an important phospholipid that makes up cell membranes and organelle membranes. It is also called cephalin because it is abundant in the brain, spinal cord, and other nervous tissues. As much as 45% of brain phospholipids consist of cephalin. Cephalin is believed to play an important role in cognition and memory. In bacteria, phosphatidylethanolamine is the major phospholipid; in animals, lecithin or phosphatidylcholine is the most abundant, but cephalin is a close second.
Like phosphatidylcholine, phosphatidylethanolamine is composed of glycerol, two fatty acids, and phosphoric acid. While phosphatidylcholine has choline attached to the phosphate group, PE has ethanolamine. The fatty acids of PE may be identical or different, but they usually occupy the 1,2 carbon positions. At times, however, they may occupy the 1,3 carbon positions.
The melting temperature of phosphatidylcholine is –20 degrees Celsius, while that of phosphatidylethanolamine is –16 degrees Celsius. PE has a higher melting point, so it is less fluid. Phosphatidylethanolamine is believed to lend a lateral pressure to the lipid bilayer, such that membrane proteins achieve their stable confirmation. It is also believed to support the positioning of positively charged amino acids on the inside of the membrane.
