Phosphatidylserine is also called complex nervonic acid.
PS, abbreviated as PS, is extracted from the residue of natural soybean oil extraction. It is an active substance in the cell membrane, especially present in brain cells. Its main function is to improve the function of nerve cells, regulate the transmission of nerve pulses, and enhance brain memory function. Due to its strong lipophilicity, it can quickly enter the brain through the blood-brain barrier after absorption, playing a role in soothing vascular smooth muscle cells and increasing blood supply to the brain.
Phosphatidylcholine, abbreviated as PC, is a zwitterionic molecule composed of a hydrophilic head and a hydrophobic tail. It is a type of phospholipid with a choline group inserted at the head.
Phosphatidylcholine is an important component of biofilms and can be easily extracted from various sources, such as egg yolk and soybeans, with the usual reagent used for extraction being hexane.
Phosphatidylcholine is also an important component of brown adipose tissue in animal and plant tissues. Dipalmitoyl phosphatidylcholine is the main component of alveolar surfactant and is often used to measure the L/S ratio (lecithin/sphingomyelin ratio) to measure the maturity of embryonic lung development. Although all animal and plant cells contain phosphatidylcholine, most bacterial cells do not contain phosphatidylcholine, such as E. coli. Purified phosphatidylcholine is often used for economic and commercial purposes.
