1-Oleoyl-2-palmitoyl-phosphatidylcholine. Phosphatidylcholines (PC) are a class of phospholipids that incorporate choline as a headgroup.They are a major component of biological membranes and can easily be obtained from a variety of readily available sources, such as egg yolk or soybeans, from which they are mechanically or chemically extracted using hexane.
Choline is an essential nutrient for humans and many other animals. [2] Humans are capable of some de novo synthesis of choline but require additional choline in the diet to maintain health. Dietary requirements can be met by choline by itself or in the form of choline phospholipids, such as phosphatidylcholine. [2]
Phosphocholine is an intermediate in the synthesis of phosphatidylcholine in tissues. Phosphocholine is made in a reaction, catalyzed by choline kinase, that converts ATP and choline into phosphocholine and ADP. Phosphocholine is a molecule found, for example, in lecithin.

Phosphatidylcholine is the major phospholipid in eukaryotic membranes. Phosphatidylcholine is important for a variety of function in eukaryotes such as facilitating the transport of cholesterol through the organism, acting as a substrate for the production of second messengers and as a cofactor for the activity of several membrane-related ...
Where phosphatidylcholine is the principal phospholipid in animals, phosphatidylethanolamine is the principal one in bacteria.One of the primary roles for phosphatidylethanolamine in bacterial membranes is to spread out the negative charge caused by anionic membrane phospholipids.
A 23-year-old hiker who survived 13 days lost in the Australian wilderness after stumbling on two granola bars has thanked his rescuers for enduring “tough conditions” to find him.
Lysophosphatidylcholines are produced within cells mainly by the enzyme phospholipase A2, which removes one of the fatty acid groups from phosphatidylcholine to produce LPC. [2] Among other properties, they activate endothelial cells during early atherosclerosis .
