Syn.: trimethylvinylammonium hydrate. A highly poisonous alkaloid, C5H13NO = (CH3)3:N (CH.CH2 )- (OH), produced by the chemical decomposition of protagon, and occurring in putrefying meat and in the putrefaction by which certain esculent fungi are rendered poisonous. It is very poisonous and its action is physiologically intermediate between that of muscarin and curare, producing dilated pupils, profuse secretions, acceleration followed by paralysis of respiration, and general convulsions preceding death. Atropin antagonizes its effect on the heart and the glandular system only. The n. of commerce consists of a mixture, in various proportions, of cholin and n., and the term n. is sometimes applied to the former base. [Gr.]
