Conformational Analysis: Steroids - basic

Progesterone is the most important of the progestins that are responsible for preparing the uterus for implantation of a fertilized egg. Using the structure and image below, determine the conformation of each of the designated substituents. (Use the carbon atom numbering from the image on the left.) Hb at C7: Methyl at C10: Hb at C11: Testosterone (along with androsterone) is the principal male sex hormone responsible for development of secondary male sex characteristics. Using the structure and image below, determine the conformation of each of the designated substituents. (Use the carbon atom numbering from the image on the left.) Ha at C7: Methyl at C10: Ha at C11
