Metabolite Identification
Common NamePristanal
DescriptionPristanal belongs to the class of organic compounds known as acyclic diterpenoids. These are diterpenoids (compounds made of four consecutive isoprene units) that do not contain a cycle. Thus, pristanal is considered to be an isoprenoid lipid molecule. Pristanal is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Pristanal can be converted into pristanic acid through the action of the enzyme fatty aldehyde dehydrogenase. In cattle, pristanal is involved in the metabolic pathway called the phytanic Acid peroxisomal oxidation pathway.

General function:
Energy production and conversion
Specific function:
Oxidizes medium and long chain saturated and unsaturated aldehydes. Metabolizes also benzaldehyde. Low activity towards acetaldehyde and 3,4-dihydroxyphenylacetaldehyde. May not metabolize short chain aldehydes. Can use both NADP(+) and NAD(+) as electron acceptor. May have a protective role against the cytotoxicity induced by lipid peroxidation.
