5alpha-Androst-16-en-3-one Chemical Properties,Uses,Production
Uses
5α-Androst-16-en-3-one is a mammalian pheromone released as a volatile chemical cue in boar saliva to facilitate social and sexual interactions. It has been used to prime sexual behavior of sows in estrus for mating or artificial insemination. 5α-androst-16-en-3-one is also found in human sweat and urine and has been used to study receptor-mediated odorant detection and the genetic basis for anosmias.
Uses
5α-Androst-16-en-3-one has been used:
- to quantify its concentration in various fat tissues
- to study its trigeminal percept and implications on the rate of specific anosmia
- to study the effects of immunocastration on meat quality and sensory properties of pork bellies
Definition
ChEBI: 5alpha-androst-16-en-3-one is an androstanoid that is 5alpha-androst-16-ene substituted by an oxo group at position 3. It is a steroid pheromone found in high concentrations in the saliva of male pigs,. It has a role as a pheromone and a mammalian metabolite. It is a 3-oxo steroid and an androstanoid. It derives from a hydride of a 5alpha-androst-16-ene.
General Description
5α-Androst-16-en-3-one (androstenone) is a mammalian pheromone found in boar saliva, human sweat, and human urine.
