Biochemistry of Steroid Hormones

Abstract
This review discusses recent work on the biosynthesis of steroid hormones and the pathways and enzymes involved in their transformations in vivo and in vitro. Emphasis has been placed upon the discussion of new pathways and enzymatic mechanisms. Studies directed toward a better understanding of the mode of action of the steroid hormones will also be considered in some detail. The fact that metabolic pathways are common to many species, to many tissues, and for several classes of steroid hormones has raised serious problems in the organization of this review. It is intended that the tabular presentation of data will give a broad picture, whereas in the text special aspects have been selected for more detailed discussion.
