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

Boar taint in entire male pigs remains a problem for fresh pork production. Since castration of pigs will be prohibited in the future on animal welfare reasons, attempts are made to detect boar taint pre and post mortem. Post mortem

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

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

Specific anosmia is a term that describes an inability to perceive a particular odorant in the context of an otherwise normal olfactory acuity. The most common example, for the odor of androstenone, has been ascribed a prevalence ranging from 2
