Detailed explanation-1: -Gonane, also known as steran or cyclopentanoperhydrophenanthrene, the simplest steroid and the nucleus of all steroids and sterols, is composed of seventeen carbon atoms in carbon-carbon bonds forming four fused rings in a three-dimensional shape.
Detailed explanation-2: -Steroids have a four-fused-ring structure and have a variety of functions. Cholesterol is a steroid found in mammals that is needed for the formation of cell membranes, bile acids, and several hormones.
Detailed explanation-3: -Estrogens are steroid hormones. The estrane steroid nucleus, which is common to all estrogens and distinct from other classes of steroids such as androgens and progestins, contains 18-carbon atoms arranged into four rings as shown in Fig.
