Androsterone CAS:53-41-8

Androsterone, vel 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone and weak androgen with a potency that is approximately 1/7 quod testosteron. Insuper, converti potest ad dihydrotestosterone (DHT) from 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstenedione and testosteron, et sic, can be considered to be a metabolic intermediate in its own right.Androsterone is one of the androgens, which are steroid hormones that affect the masculinization of the fetus and child and that maintain or create masculine traits in adults. Testosterone is the most active and abundant of the androgens. Androsterone was originally isolated from male urine in very small amounts. Many scientists believe it to be a metabolic byproduct of the breakdown of testosteron, and many scientists who study pheromones think it might be active in human relations.

A molecule of androsterone is very similar to testosteron. It consists of three six-member carbon rings and one five member ring joined along common sides. Formula hypothetica est C19 H30 O2. Habet beta-isomer nomine epiandrosterone, in which an hydroxyl group occupies a different geometric position. The ratio of androsterone to epiandrosterone is thought to be important in how masculine behavior is interpreted by others

Pheromones noti sunt in insecto mores. Partes suas in animal coitu, navigationem et nidum praesidium studuit, et activae compositae sunt solitariae. Pheromones sunt ex quodam insecto escae. Their effect on mammal behavior patterns is less well understood.
