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]
Phosphatidylcholine is the major component of lecithin. It is also a source for choline in the synthesis of acetylcholine in cholinergic neurons. Phospholipids [ 1 ] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids , joined by an alcohol residue ...
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 ...

Phosphatidylcholine molecules form ~85% of the lipid in surfactant and have saturated acyl chains. Phosphatidylglycerol (PG) forms about 11% of the lipids in the surfactant, it has unsaturated fatty acid chains that fluidize the lipid monolayer at the interface. Neutral lipids and cholesterol are also present.
An example of a phosphatidylcholine, a type of phospholipid in egg lecithin. Red - choline and phosphate group; Black - glycerol; Green - unsaturated fatty acid; Blue - saturated fatty acid. Egg lecithin is a type of lecithin, a group of compounds primarily containing phospholipids, that is derived from eggs.
