Explain your reasoning. Multiple Ring Structures Background Information 1. Organic chemists use many shortcuts in drawing complex molecules. They often do not include the letter C for carbon , for example. Cholesterol , shown below, is a steroid .
Steroids are one type of molecule in the class of compounds known as lipids .
Cholesterol plays an important role in membrane formation. The bonds between the carbons are shown. In one ring there are two carbon atoms connected by a double bond. Draw an arrow to point at the double bond in the drawing. To further simplify this drawing, none of the hydrogen atoms have been drawn.
