Experimenting with lecithin

JibbyDee - 10-12-2011 at 16:16

I've been taking lecithin as a choline supplement as well as its antioxidant properties. I noticed it has quite the molecular structure:

so naturally, having a depraved urge to hydrolyse every hydrolysable compound I come across, I must hydrolyse it. So there are two carboxyl esters and one phosphate ester that I can hydrolyse. I'm not very interested in two fatty acid fragments or the glycerol fragment this will yield, but I'm interested in the ammonium phosphate betaine fragment. Ethyltrimethylammonium phosphate. I have no idea where I'm going with this, like I said I'm just satisfying my urge to hydrolyze this compound, does anyone have any ideas on what I can use this betaine for? I've never tried isolating a betaine for, I know very little about them besides that they make good osmolytes.

EDIT: I didn't think this through, the phosphate group has 2 hydrolyzable atoms so hydrolysing it will yield choline and phosphoric acid, not a betaine. Is there a way to selectively hydrolyze only the carboxylic esters, leaving the phosphate ester intact?

It almost looks like a dancing person!

Just as any phospholipid molecule in cell membranes...
