App Description

Androgen Hormones Biosynthesis Tutor is an app designed to help you learn and memorize the structures and biosynthetic pathways of the androgen hormones leading to and including testosterone, the enzymes responsible for these chemical conversions and their locations, as well as steroid chemical structure nomenclature and carbon numbering.
These structures and reactions describe critically important androgen hormones starting from the initial reactant Pregnenolone and include Progesterone, Dehydroepiandronsterone, Androstenedione through to Testosterone.

You will see the entire network of biosynthetic pathways and you choose each molecule by name or each name from each displayed molecule; instead of studying each individual pathway. If you choose the correct answer then the molecule name or molecule structure will be highlighted in green. If you choose wrongly then the wrong answer will display temporarily and then revert to the displayed name or structure 'question'. Some screens should be viewed in landscape mode and some should be viewed in portrait mode for best viewing. On smaller screen sizes all that you need to do is drag to see more of the View.

This app will be a helpful study aid for your Endocrinology, Physiology, and Biochemistry courses and exams.
