phosphatidylethanolamines

Glycerophospholipids, cephalins (Phosphatidylethanolamines (egg)) are a mixture of phosphatidylethanolamines isolated from eggs, with various fatty acyl groups at the sn-1 and sn-2 positions. Glycerophospholipids and cephalins can be completely hydrolyzed to obtain 1 mol of glycerol, phosphoric acid, ethanolamine and 2 mol of fatty acids. Phosphatidylethanolamines play a role in membrane fusion and disassembly of contractile rings during cell division, regulating membrane curvature. Phosphatidylethanolamines are able to transmit infectious prions without the help of any proteins or nucleic acids. One of the main roles of Phosphatidylethanolamines in bacterial membranes is to disperse the negative charges caused by anionic membrane phospholipids.

Phosphatidylethanolamines (bovine) are a mixture of phosphatidylethanolamines isolated from bovine brain with different fatty acyl groups at the sn-1 and sn-2 positions.Phosphatidylethanolamines (bovine) are the most abundant phospholipids in prokaryotes and the second most abundant in mammalian, plant and yeast cell membranes. Phosphatidylethanolamines (bovine) are the most abundant phospholipids in prokaryotes and the second most abundant phospholipids in the cell membranes of mammals, plants, and yeast, accounting for about 25% of the total mammalian phospholipids.

Phosphatidylethanolamine (PE) contains phospholipids found in mammals, formed by decarboxylation of phosphatidylserine.
