The enolization of pyruvate and the reversible dehydration of pyruvate hydrate were studied at 25.0 o C using spectrophotometric methods. The enolization of pyruvate was followed at 353 nm by monitoring the rate of uptake of triiodide ion. The dehydr

Xanthine oxidase (XO), catalyzes the sequential oxidation of hypoxanthine to xanthine and then to uric acid. The enzyme also catalyzes the oxidation of aldehydes to their corresponding carboxylic acids. In the present work we investigate the extent o

The xanthine oxidase catalyzed oxidation of hypoxanthine was followed by monitoring the formation of uric acid at 290 nm. Inhibition of xanthine oxidase occurs in aqueous solutions of folic acid methotrexate and aminopterin. These compounds are known

Many carbonyl substrates of oxidoreductase enzymes undergo hydration and enolization so that these substrate systems are partitioned between keto, hydrated (gem-diol), and enol forms in aqueous solution. Some oxidoreductase enzymes are subject to inh
