Metabolite Identification
Common NameAndrostanediol
DescriptionAndrostanediol is a metabolite of dihydrotestosterone, itself a metabolite of testosterone. Androstanediol is implicated in the regulation of gonadotropin secretion. As a metabolite of dihydroxytestosterone formed in the peripheral tissues, androstanediol and androstnediol-glucuronide can be used to estimate peripheral androgen activity. Androstanediol is a potential GABA (A) receptor-modulating neurosteroid with anticonvulsant properties and hence could act as a key neuromodulator in the central nervous system. It is considered that androstanediol has hedonic effects; therefore it is anticipated that androgens that are readily metabolized to androstanediol may have higher abuse potential than androgens that are not as easily metabolized to androstanediol. These results add to the growing literature indicating that athletes and non-athletes may be at considerable risk when they abuse androgens. (PMID: 11500254 , 16040068 , 11744084 ).

General function:
Involved in oxidoreductase activity
Specific function:
Oxidoreductase with a preference for NAD. Oxidizes all- trans-retinol and 13-cis-retinol to the corresponding aldehydes. Has higher activity towards CRBP-bound retinol than with free retinol. Oxidizes 3-alpha-hydroxysteroids. Oxidizes androstanediol and androsterone to dihydrotestosterone and androstanedione. Can also catalyze the reverse reaction
