allocholic acid

Allocholic acid is a fetal bile acid found in vertebrates and reappears during liver regeneration and carcinogenesis. It is also a potent and specific stimulant of the adult olfactory system.

Allocholic acid (Standard) is a reference standard for research and analysis in studies involving Allocholic acid. Allocholic acid is a major component in bile from the river carpsucker, Carpiodes carpio. Allocholic acid is a potent and specific stimulant of the adult olfactory system and function as migratory pheromones in lamprey.

Tauroallocholic acid sodium is a type of bile acid.

Petromyzonol is a tetrahydroxy stearol which serves as the primary spawning pheromone in adult sea lamprey. It is produced in the bile of sea lamprey larvae from the bile acid precursor allocholic acid. While the adult sea lamprey is relatively insensitive to petromyzonol itself, the C-24 sulfate ester (petromyzonol sulfate) is a pheromone and a spawning chemoattractant which can be detected at very low concentrations by lamprey olfactory chemoreceptors. Petromyzonol, petromyzonol sulfate, and allocholic acid are all found in water samples from fresh water streams bearing larval lamprey populations.[1]
