Heres the info on PPC v PC. From the thread.

No. its NOT just choline, very far from that. It is a polyunsaturated fatty acid attached to phosphatidyl-choline. I do not like to mention any brand names here, but this is too important to let it go into nowhere. Check the brand name hepatopro. This is exactly that PPC compound mentioned in the article above.
No, lecithin ("choline in food?")was used as a control in the Charles Lieber trials and failed to give the same effect, not surprisingly, considering the importance of the fatty acid tail to be polyunsaturated for membane fluidity and functionality
As mentioned before : PPC its NOT just choline, very far from that. It is a polyunsaturated fatty acid attached to phosphatidyl-choline. "Lecithin" is sometimes used synonomous with phosphatidylcholine without the fatty acid, sometimes with it but it is a compound with A SATURATED fatty acid. And sometimes just with a lot of fat, without the phosphatidylcholine.
I think you can join the dots from there.
I am trying to stay outa this.
All the Best
