Abstract The development of prostate carcinoma is associated with alterations in fatty acid metabolism. α-Methylacyl-CoA racemase (AMACR) is a peroxisomal and mitochondrial enzyme that catalyses interconversion between the (S)/(R)-isomers of a range of α- methylacyl-CoA thioesters. AMACR is involved in the β-oxidation of the dietary branched- chain fatty acids and bile acid intermediates. It is highly expressed in prostate (more than ...
