The effect of substitution at the 9 position of the electrochemical oxidation of xanthine.
(1980)
The electrochemical oxidation of xanthosine was shown to be nearly identical to that of 9-methylxanthine. The major difference being the ribose substituent in the observed products.
Development of procedures for the determination of catecholamines, indoleamines, related metabolites, and monoamine oxidase activity.
(1981)
A procedure was also employed for the determination of monoamine oxidase activity in tissue samples. Focusing on the analysis of the acidic metabolites of dopamine and/or 5-hydroxytryptamine, preincubation and incubation ...
Electrochemical and enzymatic oxidation of tryptophan and 7-methyluric acid ; and, spectroelectrochemical search for a tertiary alcohol intermediate in the electrochemical oxidation of uric acid /
(1985)
Part III describes the spectroelectrochemical evidence for the tertiary-alcohol intermediate formation during the electrochemical oxidation of uric acid. Electrochemical reduction of the tertiary-alcohol intermediate in ...
Electrochemistry of methylated pterins :
(1982)
6,7-Dimethyl-5,6,7,8-tetrahydropterin (6,7-DMTHP) is an effective and widely used pseudo cofactor for phenylalanine hydroxylase in the hydroxylation reaction of phenylalanine. 6,7-DMTHP and other tetrahydropterins methylated ...
Development of methodology for the determination of catecholamines, indoleamines, and related hydroxylating enzymes.
(1980)
This study was concerned with the development and improvement of analytical procedures using liquid chromatography with electrochemical detection for the determination of activity of tyrosine hydroxylase, tryptophan ...
Optimization of liquid chromatography with electrochemical detection of three micron reversed-phase column for neurochemical determinations /
(1984)
Liquid chromatography with electrochemical detection has become an established technique for the determination of catecholamines, indoleamines, and related enzymes. Previous work in this area has utilized lower efficiency ...
Differential pulse voltammetric oxidation of polyinosinic acid and its components
(1983)
Oxidation of 6-methyl-5,6,7,8-tetrahydropterin (6-MTHP) and 6-methyl-5,6,7,8-dihydropterin (6-MDHP) was studied using electrochemical techniques. 6-MTHP is electrolyzed in a 2e-2H('+) quasi-reversible process to an unstable ...
