High-performance liquid chromatographic determination of alpha-keto acids in plasma with fluorometric detection. 1983

T Hayashi, and H Tsuchiya, and H Naruse

This paper describes a sensitive high-performance liquid chromatographic method for the quantitative determination of alpha-keto acids in plasma using a fluorescence detector. This method is about ten times more sensitive than that reported in a previous paper. Only 50 microliters of plasma are needed for the determination of alpha-keto acids. However, p-hydroxyphenylpyruvic acid could not be analysed because the quinoxalinol derived from it does not exhibit fluorescence.

D008375	Maple Syrup Urine Disease	An autosomal recessive inherited disorder with multiple forms of phenotypic expression, caused by a defect in the oxidative decarboxylation of branched-chain amino acids (AMINO ACIDS, BRANCHED-CHAIN). These metabolites accumulate in body fluids and render a "maple syrup" odor. The disease is divided into classic, intermediate, intermittent, and thiamine responsive subtypes. The classic form presents in the first week of life with ketoacidosis, hypoglycemia, emesis, neonatal seizures, and hypertonia. The intermediate and intermittent forms present in childhood or later with acute episodes of ataxia and vomiting.
