WebFatty acid α −oxidation pathway is a multistep process catalyzed by four peroxisomal enzymes: 1. Phytanic acid is activated to phytanoyl-CoA by a peroxisome-associated phytanoyl-CoA synthetase. WebThe peroxisomal straight-chain acyl-CoA oxidase enzyme plays a role in the breakdown of certain fat molecules called very long-chain fatty acids (VLCFAs). Specifically, it is involved in the first step of a process called the peroxisomal fatty acid beta-oxidation pathway.
