Presence of cobalamin analogues in animal tissues.
Cobalamin (Cbl, vitamin B-12) has been extracted and isolated from a number of animal tissues by using (i) reverse-affinity chromatography on R protein-Sepharose followed by adsorption to and elution from charcoal-coated agarose and (ii) paper chromatography. Radioisotope dilution assays showed that only 75-97% of the Cbl chromatographed in the position of crystalline Cbl. The remaining 3-25% w...
متن کاملMetabolism of Propionic Acid in Animal Tissues
The conversion of propionyl coenzyme A to succinyl-CoA involves carboxylation to methylmalonyl-Cob (a), isomerization of methyhnalonyECoA (a) to its enantiomorph methyhnalonylCoA (b), and isomerization of the latter to succinyl-CoA (3). Since methylmalonyl-CoA (a) has recently been shown to have the D configuration (4, 5), the reversible reaction catalyzed by methylmalonyl-CoA racemase will hen...
متن کاملThe Estimation of Amino Acid Nitrogen in Animal Tissues
Of the existing methods for the determination of amino acid nitrogen in animal tissues, those of Folin and Denis (1) and of Van Slyke (2) are best known and most extensively employed. Both of them are long and tedious and call for rather large tissue samples. Also methyl alcohol containing zinc chloride is employed as an extractive by Folin and Denis and ethyl alcohol as a protein precipitant b...
متن کاملThe Quantitative Estimation of Nicotinic Acid in Animal Tissues
During the last few years the Konig reaction (1) between pyridine derivatives, cyanogen bromide, and aromatic amines has been made the basis of a number of procedures for the quantitative estimation of nicotinic acid in tissues. After extensive experience with several of these methods we have concluded that none is without severe defect and have attempted to formulate a more satisfactory proced...
