What forms the basis for the body's steroids?

The basis for the body's steroids is cholesterol, a type of lipid. Cholesterol serves as a precursor for the synthesis of various steroid hormones, including corticosteroids, sex hormones, and anabolic steroids. These hormones play crucial roles in regulating metabolism, immune function, and reproductive processes. The body synthesizes cholesterol primarily in the liver, but it can also be obtained from dietary sources.
