- A poisonous organic base (a ptomaine) formed in the
decomposition of protagon with boiling baryta water, and in the
putrefraction 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.
