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: -Steroid numbering system and nomenclature. All steroids are related to a characteristic molecular structure composed of 17 carbon atoms-arranged in four rings conventionally denoted by the letters A, B, C, and D-bonded to 28 hydrogen atoms.
Detailed explanation-3: -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.
