So, we see that steroid hormones control many vital functions in your body. Of course, we wouldn't have these or any steroids if we did not have cholesterol. It could be said that the most important steroid molecule in your body is cholesterol , because cholesterol is the parent compound from which steroids are derived. It is basically the precursor for steroid hormones and other steroids. We see by looking at the structure of cholesterol that it is a steroid, because it has the four rings of carbon atoms. Attached to the rings we see a hydrocarbon tail and a hydroxyl group . Cholesterol is a 27-carbon steroid and has a molecular formula of C27H45OH.
In addition to the mentioned side effects several others have been reported. In both males and females acne are frequently reported, as well as hypertrophy of sebaceous glands, increased tallow excretion, hair loss, and alopecia. There is some evidence that anabolic steroid abuse may affect the immune system, leading to a decreased effectiveness of the defense system. Steroid use decreases the glucose tolerance, while there is an increase in insulin resistance. These changes mimic Type II diabetes. These changes seem to be reversible after abstention from the drugs.
