Biosynthesis of Estrogens

Abstract
The formation of estrogens and phenolic material from a large number of do Cis, C19 and C2i steroids and related structures has been investigated, employing a human placental microsomal preparation supplemented with TPNH and oxygen. The data from the incubation of 2 C 14-labeled androgens are included. There is a discussion of possible biosynthetic pathways for the estrogens.
