Neurine \Neu"rine\ (? or ?), n. [Gr. ney^ron a nerve.] (Physiol. Chem.) A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefaction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide. [Written also neurin.]

Wikipedia
Neurine is an alkaloid found in egg yolk, brain, bile and in cadavers. It is formed during putrefaction of biological tissues by the dehydration of choline. It is a poisonous, syrupy liquid with a fishy odor.
Neurine is a quaternary ammonium salt with three methyl groups and one vinyl group attached to the nitrogen atom. Synthetically, neurine can be prepared by the reaction of acetylene with trimethylamine. Neurine is unstable and decomposes readily to form trimethylamine.
