WebThe Kennedy pathway, which includes the transformation of choline to citicoline, by way of phosphorylcholine, produces phosphatidylcholine when condensed with diacylglycerol. Phosphatidylcholine can also be produced by the methylation pathway, where phosphatidylethanolamine is sequentially methylated. [25] See also [ edit] WebOct 28, 2024 · Acetylcholine synthesis The synthesis of acetylcholine is actually fairly simple as a whole, yet complex in the details. To make acetylcholine we need choline and an acetyl group. The preferred source for the acetyl group is acetyl CoA which is derived from pyruvate, the end product of glycolysis. layby australia online
