Work

Many molecules appear in two different reversed forms that have different chemical and biological effects. Through special catalysts - substances that facilitate chemical reactions without being consumed in them - it is possible to bring about a process in which only one of the reversed forms is produced. In 1968 William Knowles discovered that certain metals had this effect during hydrogenation - reactions in which hydrogen gas is added to a chemical compound. Among other things, this enabled production of L-dopa medication to treat Parkinson's disease.
