From The Collaborative International Dictionary of English v.0.48 [gcide]:

  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}.]
