General description

Metabolite of norepinephrine.

Application

DL-3,4-Dihydroxymandelic acid was used in the simultaneous analysis of 4-hydroxy-3-methoxymandelic acid and 4-hydroxy- 3-methoxyphenylacetic acid in urine. It was also used to study the changes in body temperature.

After norepinephrine (NE) is deaminated by monoamine oxidase (MAO), the aldehyde formed is either metabolized to 3,4-dihydroxy-mandelic acid (DHMA) by aldehyde dehydrogenase or is converted to 3,4-dihydroxyphenylglycol (DHPG) by aldehyde or aldose reductase. The present study examined the effects of

A quantitative assay for the diphenol oxidase activity of tyrosinase (EC 1.14.18.1) using high-pressure liquid chromatography with electrochemical detection is described. The assay is based on the observation (M. Sugumaran, 1986, Biochemistry 25, 4489-4492) that tyrosinase catalyzes the oxidative decarboxylation

We describe a rapid, reliable "high-performance" liquid-chromatographic method of simultaneously analyzing for 4-hydroxy-3-methoxymandelic acid (I) and 4-hydroxy-3-methoxyphenylacetic acid (II) in urine. Paired-ion chromatography and amperometric detection are used in the method. A 5-mL aliquot of urine is adjusted to pH

3,4-Methylenedioxymethamphetamine (MDMA, Ecstasy) is excreted in human urine mainly as conjugates of its metabolites 3,4-dihydroxymethamphetamine (DHMA) and 4-hydroxy-3-methoxymethamphetamine (HMMA). The glucuronidation kinetics of HMMA showed high capacities, but also high K(m) values, unlikely to be reached after recreational user's doses.
