Quantitation of homogentisic acid in normal human plasma

Biomedical Applications, 1996
A new stable isotope dilution gas chromatograph-mass spectrometric method of analysis of homogentisic acid is described. Using this method, homogentisic acid is measured for the first time in normal human plasma. The assay of sera from nine normal individuals yielded a range of values from 2.4 to 12 ng/ml.

The production of homogentisic acid out of phenylacetic acid byAspergillus niger

Antonie Van Leeuwenhoek, 1951
With the aid of the replacement culture technique it was found that a strain ofAspergillus niger was able to produce homogentisic acid out of phenylacetic acid with a yield upto 15.7 % of the theoretical amount.

Chemiluminescence during the oxidation of homogentisic acid

Russian Journal of Physical Chemistry A, 2011
Chemiluminescence (CL) that accompanies the autooxidation of homogentisic acid in the presence of an alkali was studied. Data on the red shift of the CL spectrum at increased medium polarity and the dependence of the luminescence intensity and light efficiency on the reagent concentration were obtained.

A Synthesis of Homogentisic Acid

Transactions of the Kansas Academy of Science (1903-), 1973
Homogentisic acid (2,5-dihydroxyphenylacetic acid) is the substance found in the urine in alcaptonuria, an inborn error of metabolism involving incomplete oxidation of phenylalanine and tyrosine (1). The urine of individuals afBicted with the disease turns dark owning to oxidation of the acid to substituted quinhydrone complexes.
