WebThe discovery of heroin and the development of heroin abuse are introduced. Heroin, the hydrochloride of diacetylmorphine, was discovered by acetylation of morphine. Heroin, in pharmacological studies, proved to be more effective than morphine or codeine. The Bayer Company started the production of heroin in 1898 on a commercial scale. WebProduction of diacetyl by S. cerevisiae 299 was prevented by valine, inhibited by sodium arsenite, and stimulated by pantothenic acid. Valine did not prevent the production of acetoin.
