        Build a Steroid | Percy Julian

        Learn about the molecular structure of steroids. See what happens at the molecular level when the organic steroid cortisone is produced in a laboratory from the "starter" compound diosgenin. Though it may closely resemble a given natural compound in structure, a synthetic precursor is subjected to a series of chemical reactions designed to add, subtract, or otherwise modify its atomic makeup so that it exactly matches the natural compound. Explore more about this topic, from Percy Julian.
