What are the similarities between the adrenal hormone cortisone and the synthetic corticoid prednisone?
vaieri [72.5K]

Answer:

Options a,b, c and d are correct

Explanation:

From the diagram attached in the picture below, They both have steroid nucleus since they have functional groups (such as the methyl and the ketone groups) that are spatially attached. It can also be deduced that both structures have three (3) ketone groups (CO/C=O), two (2) methyl groups (CH₃) and two (2) hydroxyl groups (OH). Hence, options a, b,c and d are correct.

However, cortisone has one (1) double bond while prednisone has two (2) double bonds.
