[A simple method for the synthesis of phosphatidylcholine with the fatty acid substituted in the 2-position]. 1976

G Schulze, and K Jung, and D Kunze, and E Egger

The preparation of PC with the 14C-fatty acids palmitic, stearic, oleic and linoleic acid at OH-group in position 2 is described. The starting material is egg yolk lecithin. By the attack of snake venom phospholiphase lyso-PC is produced which is reacylated by the appropriate fatty acid anhydride. In comparison with the methods published up to now this preparation has the advantage of higher yields and greater simplicity. By means of in vivo synthesis it is impossible to get PC species with only one fatty acid in a defined position. Working with radioactive fatty acids the specific radioactivity can be adapted to the requirements. The procedure can be made on a semi-technical scale.
