Nonadecanoic acid
Nonadecanoic acid, also known as n-nonadecanoic acid or nonadecylic acid or C19:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms, with nonadecanoic acid (its ester is called nonadecanoate) having 19 carbon atoms. Nonadecanoic acid is a very hydrophobic molecule, practically insoluble (in water). It is a solid with a melting point of 69.4°C. It can be found in bacteria, plants, and animals (including animal milk) (Nature 176:882; PMID: 14168161). It is secreted by termites (Rhinotermes marginalis) as part of its defence mechanism (Comp. Biochem. Physiol. B 71:731). Nonadecanoic acid is a C19 straight-chain fatty acid of plant or bacterial origin. An intermediate in the biodegradation of n-icosane, it has been shown to inhibit cancer growth. It has a role as a fungal metabolite.

Pristanate
Pristanic 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. Component of butterfat and sheep perinephric fat
