Soon after the famous record by Roger Maris was beaten, another baseball player, Jason Giambi and others came out to say they often used prohormones. The Congress was forced to convene a hearing after which it determined that steroids were not really a threat. Rather, it ruled out that it was the responsibility of professional sports organizations to supervise and regulate their use. The law was updated and an official definition of the term steroid was given as follow: an “anabolic steroid” means any drug or hormonal substance, chemically and pharmacologically related to testosterone (other than estrogens), progestins, corticosteroids, and dehydroepiandrosterone).
Key conclusions are the need to accomplish multiple pedagogic aims with single images, to reduce redundancy of some represented concepts, and to generally better represent the scope of actual steroid categories. For instance, a good single picture of lanosterol with ring lettering and numbering, adapted from the image at right below, could replace 5 current images and be more complete in its coverage of these conventions as well as show lanosterol for other purposes; a single panel for cholesterol with representations including a chair-type, with limited numbering and suitable legend, could replace most of the C-3 sterol images, well reinforce foregoing concepts, impress needed perspectives on steroid structure and function, and set-up later discussion of conformation; etc.
