Chapter 19, Problem 93CP

Interpretation Introduction

(a)

Interpretation:

The conversion reaction of cortisone to cortisol needs to be explained.

Concept Introduction:

Steroids are types of lipids, which consist of three 6-membered rings and one 5-membered ring. These all rings together called a steroid nucleus. Other polar and non-polar groups are bonded with these rings and are responsible for different physical and chemical properties of steroids. Cholesterol, estrogen, progestin, and androgen is one of the examples of steroid with four steroid nuclei.

Interpretation Introduction

(b)

Interpretation:

The conversion reaction of estradiol to estrone needs to be explained.
