Phytanic acid, a branched chain fatty acid, is an important component of fatty acid intake, occuring in meat, fish and dairy products. Due to its methylation, it cannot be a substrate for acyl-CoA dehydrogenase and cannot enter the mitochondrial beta oxidation pathway. Phytanic acid is instead activated to its CoA ester form by a CoA synthetase to phytanoyl-CoA, where it can begin the first cycle of alpha oxidation. Phytanoyl-CoA is a substrate for a specific alpha-hydroxylase (Phytanoyl-CoA hydroxylase), which adds a hydroxyl group to the α-carbon of phytanic acid, creating the 19-carbon homologue, pristanic acid. Pristanic acid then undergoes further metabolism through beta oxidation.
