| malic acid | HOOC-CH2-CHOH-COOH; hydroxysuccinic acid;an acid found in apples and various other tart fruits; an intermediate in the tricarboxylic acid cycle, the glyoxylate cycle, and in a shuttle system. Synonym: monohydroxysuccinic acid. (05 Mar 2000) |
| malic | <chemistry> Pertaining to, or obtained from, apples; as, malic acid. Malic acid, a hydroxy acid obtained as a substance which is sirupy or crystallized with difficulty, and has a strong but pleasant sour taste. It occurs in many fruits, as in green apples, currants, etc. It is levorotatory or dextrorotatory according to the temperature and concentration. An artificial variety is a derivative of succinic acid, but has no action on polarized light, and thus malic acid is a remarkable case of physical isomerism. Origin: L. Malum an apple: cf. F. Malique. Source: Websters Dictionary (01 Mar 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.)

| 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) |
