General description

5α-Androst-16-en-3-one (androstenone) is a mammalian pheromone found in boar saliva, human sweat, and human urine.

Application

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

CYP2A6 is one of the enzymes involved in the hepatic metabolism of a naturally produced compound, skatole, in the pig. Low CYP2A6 activity has been linked to excessive accumulation of skatole in pig adipose tissue and development of the phenomenon

Boar taint is a major obstacle when using uncastrated male pigs for swine production. One of the main compounds causing this taint is androstenone, a pheromone produced in porcine testis. Here we use microarrays to study the expression of thousands

The level of cytochrome b5A (CYB5A) in pig testis is correlated with boar taint from androstenone and an AF016388:c.-8G>T polymorphism in CYB5A has been linked with low androstenone levels in the fat of pigs. In this study, we developed a
