what does phosphatidylcholine function
When Phosphatidylcholine enters your brain, it is used to build and repair new cell membranes. The same lipid structures present in Phosphatidylcholine are also present in your cell membranes, especially those in the brain.
As a phospholipid, Phosphatidylcholine supplements are able to restore proper function to damaged brain cells. The cell membranes can be repaired and revived thanks to the high lipid content of the supplement. As these membranes are restored this makes them more fluid and less rigid.
Similarly, phosphatidic acid generated in this way from phosphatidylcholine in animals is involved in the metabolism and signalling function of phosphoinositides by activating phosphatidylinositol 4-phosphate 5-kinase, the main enzyme generating the lipid second messenger phosphatidylinositol-4,5-bisphosphate.
