The enantiomer and any two diastereomers of cholesterol are to be drawn, and the position for OH group of cholesterol as an axial or equatorial is to be identified. Concept introduction: Steroids, a group of tetracyclic lipids composed of one five-membered ring and three six-membered rings. Thesse rings are lettered by A , B , C , and D . Most of the steroids contain two angular methyl groups. These methyl groups are numbered as C18 and C19 respectively.
