Abstract
Cholesterol is catabolized to bile acids by peroxisomal β-oxidation in which the side-chain of C27-bile acid intermediates is shortened by three carbon atoms to form mature C24-bile acids. Knock-out mouse models deficient in α-methylacyl coenzyme A racemase (Amacr) or multifunctional enzyme type 2 (...
