Process in which one type of steroid, or a precursor, is converted to a related molecule using enzymes or cells as catalysts. Such transformations include the hydroxylation of progesterone using Rhizopus arrhizus, which introduces an oxygen atom at C-11.  1, record 1, English, - steroid%20bioconversion

[Pour la] biotransformation de stéroïdes, de nombreuses espèces [de bactéries] sont utilisables et peuvent catalyser des réactions spécifiques d'hydroxylation, d'époxydation, de déshydrogénation, de cyclisation, d'hydrolyse, de céto-réduction, d'isomérisation ... L'exemple le plus classique est celui de la transformation par Rhizopus arrhizus de la progestérone en 11-[alpha]-hydroxyprogestérone.  1, record 1, French, - biotransformation%20de%20st%C3%A9ro%C3%AFdes
