Descriptions:
pubchem: 11-oxotestosterone is a 3-oxo 4-steroid that is testosterone carrying an additional oxo substituent at position 11. It has a role as an androgen, a human metabolite and a marine xenobiotic metabolite. It is a 17beta-hydroxy steroid, an 11-oxo steroid, a 3-oxo-Delta(4) steroid and an androstanoid. It is functionally related to a testosterone. It derives from a hydride of an androstane.
chebi: A 3-oxo Δ<small><sup>4</small></sup>-steroid that is testosterone carrying an additional oxo substituent at position 11.
wikipedia: 11-Ketotestosterone (11-KT) is an oxidized form of testosterone that contains a keto group at the C11 position. It is related to adrenosterone, an androgen found in trace quantities in humans. In fish, 11-ketotestosterone functions as the endogenous androgenic sex hormone. In midshipman fish, 11-ketotestosterone is not present in females or Type II Males — Type II Males reach sexual maturation later, are less territorial, and have higher testosterone than Type I Males.
In mammals, 11-ketotestosterone has similar potency to testosterone as an androgen, and has been identified as an important adrenal androgen. However, unlike testosterone, it is very weakly anabolic and mostly prevents muscle breakdown as opposed to promoting muscle growth. It is synthesized from 11β-hydroxyandrostenedione and, to a lesser extent, 11-ketoandrostenedione (adrenosterone). 11-Ketoandrostenedione has notably been sold online as an androgen prohormone, usually under the name 11-oxoandrostenedione (11-OXO).
