Studies on uric acid and related compounds. III. Observations on the specificity of mammalian xanthine oxidases.
Xanthine oxidase (X0) has been thoroughly studied by many investigators and the range of possible substrates of this enzyme is well known (1, 2). In the early experiments, enzymatic activity was measured by decolorization of a suitable dyestuff such as methylene blue or by oxygen consumption. Therefore, the exact pathway of oxidation remained unknown for many substrates. The spectrophotometric ...
متن کاملStudies on Uric Acid and Related Compounds
The systematic study of the substrate specificity of mammalian xanthine oxidase has indicated a common mechanism by which various purines may be dehydrogenated (1). The results obtained also made it clear why methylated xanthines, with the exception of 1-methylxanthine (2), cannot be oxidized by xanthine oxidase to the corresponding substituted uric acids (3, 4). Therefore, another source had t...
متن کاملAnalytical Techniques for Cell Fractions. Iii. Nucleotides and Related Compounds.
The methods described in this paper are devised for the separation of the common nucleotides, nucleosides, and purine and pyrimidine bases on one column at one pH with the compounds quantitated by a sensitive automatic technique. Following the classical work of Cohn and co-workers (l-6)) nucleotides have been generally separated on anion-exchange columns at acid pH’s, nucleosides on anion-excha...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولStudies on the Cancerogenic Azo and Related Compounds *
Even in the earliest days of cancer research it was claimed that Scarlet Red and o-aminoazotoluene could accelerate epithelial proliferation, and that these chemicals, when orally administered, could cause an adenomatous proliferation in the liver. But no definite evidence was found to prove their carcinogenic effect, notwithstanding numerous experimental attempts, until, a few years ago, Sasak...
