What is 5ALPHA-ANDROST-16-EN-3-ONE?

The Uses of 5ALPHA-ANDROST-16-EN-3-ONE

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.

The Uses of 5ALPHA-ANDROST-16-EN-3-ONE

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

What are the applications of Application

5α-Androst-16-en-3-one is a mammalian pheromone

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.
