| 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) |
| vitamin A1 acid | <biochemistry> The aldehyde (retinal) has long been known to be involved in photoreception, but retinoic acid has other roles. There are cytoplasmic retinoic acid binding proteins and retinoic acid response elements that regulate gene transcription. Retinoic acid is thought to be a morphogen in chick limb bud development and in early development of the chick that probably accounts for its potent teratogenic action. Synonym: vitamin A. (03 Jul 1999) |
| glucogenic amino acid | <biochemistry> A type of amino acid with carbon chains that can be broken down into an intermediate of the citric acid cycle such as glycogen and then converted into glucose as a means of entering the normal process of carbohydrate metabolism in the body. Examples include: Glycine, alanine, arginine, and ornithine. (14 Oct 1997) |
| gluconic acid | <biochemistry> An acid with the chemical formula C6H12O7. at room temperature, it is a colourless crystal, it melts at 131 degrees Celsius. It can be made by the oxidation of glucose. It will dissolve in water and alcohols. It is used in pharmaceuticals and some food products, as a cleanser, and as a catalyst in textile printing. (09 Oct 1997) |
| cellular retinoic acid binding protein | <protein> A cytoplasmic fatty acid binding protein that acts as an initial receptor for the putative morphogen, retinoic acid. (18 Nov 1997) |
| cellulosic acid | See: oxidised cellulose. (05 Mar 2000) |
| repetitive sequences, nucleic acid | Nucleotide sequences present in multiple copies in the genome. They include direct, inverted, tandem, and terminal repeat sequences and the alu family repeat (named for the restriction endonuclease cleavage enzyme alu I). (12 Dec 1998) |
| pectic acid | The d-isomer is an oxidation product of d-galactose, in which the 6-CH2OH group has become a -COOH group; occurs in many natural products (e.g., pectins). Synonym: pectic acid. (05 Mar 2000) |
| glucuronic acid | <biochemistry> A glucose molecule which has had its sixth carbon atom (of six total) oxidized. It has the chemical formula C6H10O7. (09 Oct 1997) |
