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.
Modern lipid profiling employs more absolute methods of analysis, with NMR spectroscopy, particularly 31 P-NMR, ... egg PC (Egg lecithin), egg PG, soy PC, ...
Egg-derived lecithin is not usually a concern for those allergic to eggs since commercially available food grade egg lecithin is devoid of allergy-causing egg proteins. Egg lecithin is not a concern for those on low-cholesterol diets, because the lecithin found in eggs markedly inhibits the absorption of the cholesterol contained in eggs. [6]
Phosphocholine is a natural constituent of hens' eggs (and many other eggs) often used in biomimetic membrane studies. [4] [5] See also. Alkylphosphocholines;
For two-tailed PC lipids, this ratio is nearly one so the intrinsic curvature is nearly zero. If a particular lipid has too large a deviation from zero intrinsic curvature it will not form a bilayer and will instead form other phases such as micelles or inverted micelles. Addition of small hydrophilic molecules like sucrose into mixed lipid ...
Common sources include egg yolk, [7] marine foods, soybeans, [7] milk, rapeseed, cottonseed, and sunflower oil. It has low solubility in water, but is an excellent emulsifier. In aqueous solution, its phospholipids can form either liposomes, bilayer sheets, micelles, or lamellar structures, depending on hydration and temperature.
Theodore Gobley (1847) discovered phospholipids in mammalian brain and hen egg, called by him as "lecithins". Thudichum discovered in human brain some phospholipids , glycolipids (cerebroside) and sphingolipids (sphingomyelin). [9] The terms lipoid, lipin, lipide and lipid have been used with varied meanings from author to author. [15]
POPC (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine) is a phosphatidylcholine.It is a diacylglycerol phospholipid.It is an important phospholipid for biophysical experiments and has been used to study various subjects such as lipid rafts.
