It is now known, however, that chlorophyll contains neither choline nor phosphorus, the earlier observations being due to mixtures of various other materials with the true chlorophyll in the extracts which were examined.
Choline occurs alone in the seeds and fruits of many plants, sometimes as the free amine, but more often as a constituent of lecithin (see page 141).
Betaine and choline often occur together in the germs of many plants.
As recently as 1908, it was asserted that chlorophyll is a lecithin-like body, yieldingcholine and glycero-phosphoric acid on hydrolysis.
Try to buy the kind of lecithin that has the highest phosphatidyl choline content because this substance is the second benefit of taking lecithin.
Phosphatidyl choline is another precursor used by the body to build acetylcholine and helps maintain the nervous system.
It may be synthetically prepared by oxidizing choline with chromic acid (O.
It may be obtained synthetically by oxidizing choline with dilute nitric acid (O.
According to Kobert, Amanita muscaria contains, besides choline and muscarine, a third alkaloid, pilz-atropin.
According to Kobert the substance formed from choline on the decay of the mushrooms containing it is not muscarine, but a very closely related alkaloid, neurin.
They all consist of glyceryl esters containing two fatty acid radicals and the phosphoric acid radical in which one of the residual hydrogens is replaced by the choline group.
It is decomposed by alkalies with the formation of choline and trimethylamine.
From choline it may be separated by recrystallising the mercuric precipitate from hot water.
It is usually accompanied by choline, from which it can be separated by converting the bases into hydrochlorides, choline hydrochloride being soluble in absolute alcohol, neuridine scarcely so.
The cholinegroup consists of choline, neurine, betaine, and muscarine.
Thus, all three parts were identified, and Strecker put them together to construct a chemical formula for lecithin, glycerophosphoric acid combined with a fatty acid and with choline (a hydrate of neurine).
Enzyme B attacks this residue and splits off the remaining fatty acid group from it, enzyme C liberates only the choline from lecithin, and enzyme D opens lecithin at the ester bond between glycerol and phosphoric acid.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "choline" in a variety of sentences. We hope that you will now be able to make sentences using this word.
