Common NamePristanic acid
DescriptionPristanic acid (2,6,10,14-tetramethylpentadecanoic acid) is a terpenoid acid present at micromolar concentrations in the plasma of healthy individuals. It is also found in the lipids from many sources such as freshwater sponges, krill, earthworms, whales, human milk fat, bovine depot fat, butterfat or Californian petroleum. It is usually present in combination with phytanic acid. In humans, pristanic acid is obtained from two sources: either directly from the diet or as the alpha oxidation product of phytanic acid. At physiological concentrations pristanic acid is a natural ligand for PPARalpha. In liver, pristanic acid is degraded by peroxisomal beta oxidation to propionyl-CoA. Together with phytanic acid, pristanic acid accumulates in several inherited disorders such as Zellweger syndrome. Pristanic acid is a branched chain fatty acid that arises from the breakdown of phytanic acid. It is present at micromolar concentrations in the plasma of healthy individuals. Pristanic acid is normally degraded by peroxisomal beta-oxidation. In patients affected with generalized peroxisomal disorders, degradation of both phytanic acid and pristanic acid is impaired owing to absence of functional peroxisomes. Pristanic acid has been found to activate the peroxisome proliferator-activated receptor {alpha} (PPAR{alpha}) in a concentration dependent manner.
