| gentisic acid | 2,5-Dihydroxybenzoic acid; 5-hydroxysalicylic acid;this compound is chemically related to salicylate and aspirin (acetylsalicylate) and shares with the latter agent analgesic and anti-inflammatory properties. (05 Mar 2000) |
| receptors, retinoic acid | Proteins in the nucleus or cytoplasm that specifically bind retinoic acid or retinol and trigger changes in the behaviour of cells. Retinoic acid receptors, like steroid receptors, are ligand-activated transcription regulators. Several types have been recognised. (12 Dec 1998) |
| Gerhardt's test for acetoacetic acid | In fresh urine a red colour develops upon addition of FeCl3; no colour develops if the urine has first been boiled; this test has low specificity and sensitivity. Synonym: Gerhardt's reaction. (05 Mar 2000) |
| casamino acid | <biochemistry> The group of amino acids which results when casein, a protein found in milk, is broken down by enzymes. (09 Oct 1997) |
| gibberellic acid | <plant biology> Diterpenoid compounds with gibberellin activity in plants. at least 70 related gibberellic acids have been described and designated as a series GA1, GA2 etc. (17 Dec 1997) |
| reductic acid | 2,3-Dihydroxy-2-cyclopenten-1-one;a strong reducing product (antioxidant) formed in hot alkaline sugar solutions. (05 Mar 2000) |
| catechinic acid | <chemical> 3,3',4',5,7-flavanpentol. Extracted from uncaria gambier, acacia catechu and other plants; it stabilises collagen and is therefore used in tanning and dyeing; it prevents capillary fragility and abnormal permeability, but was formerly used as an antidiarrhoeal. Synonym: cachou; cashoo; cutch. Chemical name: 2H-1-Benzopyran-3,5,7-triol, 2-(3,4-dihydroxyphenyl)-3,4-dihydro-, (2R-trans)- (12 Dec 1998) |
| catechuic acid | <chemical> 3,3',4',5,7-flavanpentol. Extracted from uncaria gambier, acacia catechu and other plants; it stabilises collagen and is therefore used in tanning and dyeing; it prevents capillary fragility and abnormal permeability, but was formerly used as an antidiarrhoeal. Synonym: cachou; cashoo; cutch. Chemical name: 2H-1-Benzopyran-3,5,7-triol, 2-(3,4-dihydroxyphenyl)-3,4-dihydro-, (2R-trans)- (12 Dec 1998) |
| glacial phosphoric acid | An anhydride of phosphoric acid used as a reagent, and in the manufacture of zinc oxyphosphate cement for dentistry. Synonym: metaphosphoric acid. (05 Mar 2000) |
| regulatory sequences, nucleic acid | DNA sequences involved in regulating the expression of other genes. (12 Dec 1998) |
| meclofenamic acid | <chemical> A non-steroidal anti-inflammatory agent with antipyretic and antigranulation activities. It also inhibits prostaglandin biosynthesis. Pharmacological action: non-steroidal anti-inflammatory agents, cyclooxygenase inhibitors. Chemical name: Benzoic acid, 2-((2,6-dichloro-3-methylphenyl)amino)- (12 Dec 1998) |
| meconic acid | 3-Hydroxy-4-oxy-4H-pyran-2,6-dicarboxylic acid;obtained from opium; it forms soluble salts (meconates) with many of the alkaloids of opium. (05 Mar 2000) |
| glucaric acid | <chemical> D-glucaric acid. A sugar acid derived from d-glucose in which both the aldehydic carbon atom and the carbon atom bearing the primary hydroxyl group are oxidised to carboxylic acid groups. Chemical name: Glucaric acid (12 Dec 1998) |
| glucoascorbic acid | 3-Keto-d-glucoheptonofuranolactone;a compound resembling ascorbic acid but with an additional -CHOH-between C-5 and C-6 of ascorbic acid; shows toxic effects on addition to diet which apparently are not caused by ascorbic acid antagonism. (05 Mar 2000) |
