| glycolic acid dehydrogenase | <enzyme> Enzyme from human liver converts glycolate to oxalate, acceptor not identified, not oxygen; free glyoxylate is not an intermediate Registry number: EC 1.1.- (26 Jun 1999) |

| glycolic acid | <biochemistry> Hydroxyacetic acid, found in young plants and green fruits. Glycolate is formed from ribulose 1,5 bisphosphate in a seemingly wasteful side reaction of photosynthesis, known as photorespiration. (18 Nov 1997) |

| poly(glycolic acid) | A polymer of glycolic acid, used in absorbable surgical sutures. Origin: see poly- (05 Mar 2000) |
| glycolic | <chemistry> Pertaining to, or derived from, glycol; as, glycolic ether; glycolic acid. <chemistry> Glycolic acid, an organic acid, found naturally in unripe grapes and in the leaves of the wild grape (Ampelopsis quinquefolia), and produced artificially in many ways, as by the oxidation of glycol, whence its name. It is a sirupy, or white crystalline, substance, HO.CH2.CO2H, has the properties both of an alcohol and an acid, and is a type of the hydroxy acids. Synonym: hydroxyacetic acid.

| glycolic aciduria | Excessive excretion of glycolic acid in the urine; a primary metabolic defect due to deficiency of 2-hydroxy-3-oxoadipate carboxylase, resulting in excretion of glycolic and oxalic acids, leading to the clinical syndrome of oxalosis. (05 Mar 2000) |
| alpha-keto acid dehydrogenase | See: alpha-keto acid dehydrogenase. Anaerobic dehydrogenase, an enzyme (usually a pyridinoenzyme) catalyzing the transfer of hydrogen from some metabolite to some acceptor molecule (e.g., NAD+, cytochrome) other than oxygen; e.g., lactate dehydrogenase's, isocitrate dehydrogenase's, and others in EC class 1, excluding those listed under aerobic dehydrogenase.

| malic acid dehydrogenase | <enzyme> An enzyme that catalyses the conversion of (s)-malate and NAD+ to oxaloacetate and NADH. Chemical name: (S)-Malate:NAD+ oxidoreductase Registry number: EC 1.1.1.37 (12 Dec 1998) |
| norsolorinic acid dehydrogenase | <enzyme> Catalyses the conversion of norsolorinic acid to averantin Registry number: EC 1.1.1.- (26 Jun 1999) |
| iminodiacetic acid dehydrogenase | <enzyme> Catalyses the conversion of iminodiacetic acid to glycine and glyoxylate; a membrane-bound enzyme isolated from chelatobacter heintzii Registry number: EC 1.5.1.- Synonym: ida-dh, ida dehydrogenase (26 Jun 1999) |
| isocitric acid dehydrogenase | <enzyme> An enzyme of the oxidoreductase class that catalyses the conversion of isocitrate and NAD+ to yield 2-ketoglutarate, carbon dioxide, and NADH. It occurs in cell mitochondria. The enzyme requires magnesium, mn2+; it is activated by ADP, citrate, and calcium, and inhibited by NADH, NADPH, and ATP. The reaction is the key rate-limiting step of the citric acid (tricarboxylic) cycle. (the NADP+ enzyme is EC 1.1.1.42.) Chemical name: Isocitrate:NAD+ oxidoreductase (decarboxylating) Registry number: EC 1.1.1.41 (12 Dec 1998) |

| 13-hydroxyoctadecadienoic acid dehydrogenase | <enzyme> Nad-dependent enzyme from rat colon mucosa; forms 13-oxooctadecadienoic acid; inhibited by disulfiram Registry number: EC 1.1.1.- Synonym: 13-hode dehydrogenase, 13-roh dehydrogenase (26 Jun 1999) |
| lactic acid dehydrogenase | <enzyme> An enzyme with 5 forms: LDH-1 is in the heart, its blood level can rise when heart muscle is damaged. Other forms can be found in the liver, brain, kidney, skeletal muscle and bone. A useful blood test in the evaluation of many disease processes, including heart attack, liver disease, muscular dystrophy and bone disease. (27 Sep 1997) |
