Growth promotion and iron transport studies revealed that certain alpha-keto acids generated by amino acid deaminases, by enterobacteria of the Proteus-Providencia-Morganella group (of the tribe Proteeae), show significant siderophore activity. Their iron-binding properties were confirmed by the ...

Alpha-keto (α-keto) acids are used widely in feeds, food additives, pharmaceuticals, and in chemical synthesis processes. Although most α-keto acids are currently produced by chemical synthesis, their biotechnological production from renewable carbohydrates is a promising new approach. In this mini...
Branched-chain α-keto acids can be isolated from serum and urine with good recoveries when treated first with hydroxylamine. Silylation of the keto acid oximes then yields clearly identified peaks after gas chromatography. Serum branched-chain keto acids are increased ten fold above normal in patien...

Protective effect of alpha-keto acids on the oxidative hemolysis. We studied antioxidative properties of various concentrations (0.3-2 mM) of biochemically important alpha-keto acids: pyruvate, alpha-ketoglutarate, oxaloacetate, glyoxylic acid as aldehyde acid and also 2-methyl-thiazolidyne-2,4-di...
