The influence of riboflavin deficiency on absorption and liver storage of iron in the growing rat.
1. Iron absorption was measured in weanling riboflavin-deficient (RD) rats or weight-matched (WM) controls fed on appropriate diets for 7 weeks. Concentrations of radio-Fe (59Fe) in plasma were monitored every 30 min for 4 h following intragastric administration. 2. Total Fe absorption in RD rats was significantly lower than that in WM controls, and the tissues of the stomach and small intestin...
متن کاملPostnatal changes in dolichol-pathway enzyme activities in rat liver.
The activity of hepatic protein N-glycosylation was compared in rats of different ages by incubating UDP-[14C]glucose with liver microsomes. Dolichyl-phosphate [14C]glucose, [14C]glucosyl-oligosaccharide-lipid and [14C]glycoproteins formed were increased after birth to maximal levels at 2 weeks; thereafter dolichylphosphate [14C]glucose remained constant, while [14C]glucosyl-oligosaccharide-lip...
متن کاملEffects of riboflavin deficiency on the synthesis of ester forms of riboflavin in the rat lens.
A few reports were found on the riboflavin (B2) in the eye tissues in various species (1-3). Flavin compound in the eye of Rana nigromaculata concentrates in the choroid, iris, ciliary body and is not present in other parts. The amount and distribution of flavin compound in the eye varies considerably in different species of frogs (4). The presence of B2 in the lens of haddock (Gadus aeglefinus...
متن کاملClofibrate elevates enzyme activities of the tricarboxylic acid cycle in rat liver.
Activities of the tricarboxylic acid cycle enzymes were measured in subcellular fractions of liver from rats that had been fed clofibrate for 3 weeks. Large changes in these activities per gram tissue were found in the large particle fraction, which also showed an increase in total protein concentration of 76% under clofibrate treatment. The three regulatory enzymes of the cycle, namely citrate...
متن کاملEffects of riboflavin deficiency and clofibrate treatment on the five acyl-CoA dehydrogenases in rat liver mitochondria.
Rats were maintained on a riboflavin-deficient diet or on a diet containing clofibrate (0.5%, w/w). The activities of the mitochondrial FAD-dependent straight-chain acyl-CoA dehydrogenases (butyryl-CoA, octanoyl-CoA and palmitoyl-CoA) and the branched-chain acyl-CoA dehydrogenases (isovaleryl-CoA and isobutyryl-CoA) involved in the degradation of branched-chain acyl-CoA esters derived from bran...
