title: Peroxisomal beta-oxidation of fatty acids in bovine and rat liver.
abstract: Hepatic peroxisomal beta-oxidation rates were compared in liver homogenates from cows and rats during different nutritional and physiological states. Peroxisomal oxidation in liver homogenates from cows represented 50% and 77% of the total capacity for the initial cycle of beta-oxidation of palmitate and octanoate, respectively, but only 26% and 65% for rats. Lactation or food deprivation did not alter rates of hepatic peroxisomal beta-oxidation of palmitate or octanoate in cows. Fasting and clofibrate treatment increased rates of total and peroxisomal beta-oxidation of palmitate and octanoate in rat liver.
