Abstract
The effects of riboflavin deficiency on hepatic peroxisomal and mitochondrial palmitoyl-CoA oxidation were examined in weanling Wistar-strain male rats. The specific activities of peroxisomal catalase and palmitoyl-CoA-dependent NAD+ reduction were not affected by up to 10 weeks of riboflavin deficiency. In contrast, the specific activity of mitochondrial carnitine-dependent palmitoyl-CoA oxidation was depressed by 75% at 10 weeks of deficiency. The amount of peroxisomal protein per g of liver was not affected by riboflavin deficiency, whereas, expressed per liver, both riboflavin-deficient and pair-fed controls showed decreased peroxisomal protein compared with controls fed ad libitum. Hepatic mitochondria, but not peroxisomes, were sensitive to riboflavin deficiency.
