isocitric acid [¦ī·sə¦si·trik ′as·əd]
(biochemistry) HOOCCH2CH(COOH)CH(OH)COOH An isomer of citric acid that is involved in the Krebs tricarboxylic acid cycle in bacteria and plants. Isocitric Acid an organic tricarboxylic acid; one of the intermediate substrates of the tricarboxylic acid cycle. Isocitric acid forms in an organism from citric acid and cisaconitic acid as a result of enzymatic conversion. With involvement of the enzyme isocitrate dehydrogenase, isocitric acid is converted, through oxalosuccinic acid, to α-ketoglutaric acid. With the aid of the enzyme isocitratelyase in the glyoxalate cycle, isocitric acid decomposes to succinic and glyoxylic acids. Want to thank TFD for its existence?
