Chemical Information
FooDB Name1-18:3-2-18:2-phosphatidylcholine
Description1-18:3-2-18:2-phosphatidylcholine is also known as phosphatidylcholine (1-18:3-2-18:2) or 18:3-18:2-pc. 1-18:3-2-18:2-phosphatidylcholine is practically insoluble (in water) and a moderately acidic compound (based on its pKa). 1-18:3-2-18:2-phosphatidylcholine can be found in a number of food items such as black raspberry, yardlong bean, swiss chard, and sunburst squash (pattypan squash), which makes 1-18:3-2-18:2-phosphatidylcholine a potential biomarker for the consumption of these food products. 1-18:3-2-18:2-phosphatidylcholine can be found primarily in blood and saliva, as well as throughout all human tissues. In humans, 1-18:3-2-18:2-phosphatidylcholine is involved in few metabolic pathways, which include alpha linolenic acid and linoleic acid metabolism, phosphatidylcholine biosynthesis PC(18:3(9Z,12Z,15Z)/18:2(9Z,12Z)), and phosphatidylethanolamine biosynthesis PE(18:3(9Z,12Z,15Z)/18:2(9Z,12Z)).
