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.
Injection lipolysis is a controversial cosmetic procedure in which drug mixtures are injected into patients with the goal of destroying fat cells. This practice, using drugs generally based on phosphatidylcholine and deoxycholate (PCDC), evolved from the initial intravenous use of those drug formulations to treat blood disorders.
Phosphatidylcholine (in the form of PPC or DLPC), the substrate for lecithin retinol acyltransferase, which converts retinol into retinyl esters (the storage forms of vitamin A). Vitamin E may alleviate hypervitaminosis A. [34] Liver transplantation may be a valid option if no improvement occurs. [35]
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.
[17] [18] Lecithin is a mixture of fats that contains phospholipids, including phosphatidylcholine, and the human body can convert phosphatidylcholine into choline. [19] [20] [21] The choline content in lecithin can vary, but it's found that phosphatidylcholine makes up about 25 to 35 percent of lecithin. Furthermore, only about 12 percent of ...
Dipalmitoylphosphatidylcholine (DPPC) is a phospholipid (and a lecithin) consisting of two C 16 palmitic acid groups attached to a phosphatidylcholine head-group.. It is the main constituent of pulmonary surfactants, which reduces the work of breathing and prevents alveolar collapse during breathing.
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 .
