Final answer:
Steroids can have different functional groups and side chains that contribute to their diverse functions in the body.
Step-by-step explanation:
Steroids and Functional Groups
Steroids are biologically active compounds that have a core structure composed of four fused rings. These rings are designated A, B, C, and D. The functional groups and side chains attached to this core structure can vary, resulting in different types of steroids. For example, cholesterol, a steroid found in animals, has a hydroxyl group (-OH) attached to it, while testosterone, a male sex hormone, has a ketone group (-C=O) in its structure.
So, yes, steroids can have different sets of functional groups and side chains, which contribute to their diverse functions in the body.
