title: Beta-oxidation in peroxisomes of brown adipose tissue.
abstract: Peroxisomes and mitochondria from brown adipose tissue of the rat were separated by differential pelleting and isopycnic gradient centrifugation. Both fractions oxidized palmitoyl-CoA with comparable specific activities. Unlike the mitochondrial beta-oxidation the peroxisomal activity was not influenced by carbon monoxide. Peroxisomal beta-oxidation together with carnitine acetyl-transferase, which is also located in peroxisomes, might be involved in chemical thermogenesis by delivering acetyl groups to the mitochondria.
