title: The identification of 14 alpha,17 beta-dihydroxyandrost-4-en-3-one monohydrate and 14 alpha,17 beta-dihydroxyandrosta-1,4-dien-3-one monohydrate, metabolites of androstenedione in Mucor piriformis.
abstract: The microorganism Mucor piriformis transforms androst-4-ene-3,17-dione into a major and several minor metabolites. X-ray crystallographic analysis of two of these metabolites was undertaken to determine unambiguously their composition and chirality. Crystals belong to the orthorhombic space-group P2(1)2(1)2(1), with a = 7.199(4) A and a = 6.023(3) A, b = 11.719(3) A and b = 13.455(4) A, c = 20.409(3) A and c = 20.702(4) A for the two title compounds, respectively. The structures have been refined to final R values of 0.060 and 0.040, respectively.
