It is a product of the decomposition of choline, betaine, and neuridine, when these substances are distilled with potash.
Betaine and choline often occur together in the germs of many plants.
It is decomposed by alkalies with the formation of choline and trimethylamine.
The variations include the alcohol, to which the fatty acids and choline phosphate are attached.
Without the choline, lecithin would be a di-fatty acid derivative of glycero-phosphoric acid.
An atom of hydrogen from the choline, CH2, group, being replaced by hydroxyl.
From choline it may be separated by recrystallising the mercuric precipitate from hot water.
choline cho·line (kō'lēn')
A natural amine often classed in the vitamin B complex and a constituent of many other biologically important molecules, such as acetylcholine and lecithin.
