| acetohydroxamic acid | C2H5NO2; N-Hydroxyacetamide;an inhibitor of urease, used as adjunctive therapy in chronic urea-splitting urinary infections. (05 Mar 2000) |
| acetrizoic acid | <chemical> A water-soluble, iodinated radiographic contrast medium, used as sodium acetrizoate in hysterosalpingography. Pharmacological action: contrast media. Chemical name: Benzoic acid, 3-(acetylamino)-2,4,6-triiodo- (12 Dec 1998) |
| acetylsalicylic acid | <drug> An odourless, white, slightly bitter drug used to reduce pain, fever, inflammation and sometimes to prevent blood clotting. Also called aspirin. Some people cannot tolerate it because it can cause stomach bleeding, however. It is soluble in both water and alcoholand melts at 132 to 136 degrees C. (06 May 1997) |
| acetyltannic acid | An astringent used for treatment of diarrhoea. Synonym: diacetyltannic acid, tannylacetate. (05 Mar 2000) |
| acid | <chemical, chemistry> A fundamental category of many compounds whose water-based solutions have a sour taste, turn blue litmus paper red and can combine with metals to form salts. They are chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. Specific types of acids include: Arrhenius acid: any chemical that increases the number of free hydrogen ions (H+) when added to a water-based solution. The more free hydrogens produced, the stronger the acid. Bronsted or Bronsted-Lowry acid: any chemical that acts as a proton donor in a chemical reaction. Lewis acid: any chemical that accepts two electrons to form a covalent bond during a chemical reaction. (13 Nov 1997) |
| acid agglutination | The clumping together of certain microorganisms at high hydrogen ion concentration. (05 Mar 2000) |
| acid anhydride hydrolases | <enzyme> A group of enzymes that catalyze the hydrolysis of diphosphate bonds in compounds such as nucleoside di- and tri-phosphates, and sulfonyl-containing anhydrides such as adenylylsulfate. (enzyme nomenclature, 1992). Registry number: EC 3.6 (12 Dec 1998) |
| acid-ash diet | A diet consisting mainly of fruits, vegetables, and milk (with minimal amounts of meat, fish, eggs, cheese, and cereals), which, when catabolised, leave an alkaline residue to be excreted in the urine. Synonym: acid-ash diet, basic diet. (05 Mar 2000) |
| acid carboxypeptidase | <enzyme> Carboxypeptidase z (scpz gene product) isolated from absidia zychae Registry number: EC 3.4.16.1 Synonym: carboxypeptidase w, carboxypeptidase yscy, carboxypeptidase cpd-s3, ybr1015 gene product, carboxypeptidase z, scpz gene product (26 Jun 1999) |
| acid cell | One of the cell's of the gastric glands; it lies upon the basement membrane, covered by the chief cell's, and secretes hydrochloric acid that reaches the lumen of the gland through fine intracellular and intercellular canals (canaliculi). Synonym: acid cell, oxyntic cell. (05 Mar 2000) |
| acid cholesterol ester synthetase | <enzyme> Aortal enzyme, does not require exogenous ATP or CoA; reverse reaction of cholesterol esterase Registry number: EC 3.1.1.- Synonym: cholesterol ester synthetase (26 Jun 1999) |
| acid-citrate-dextrose | A citrate anticoagulant used for the collection and preservation of whole blood. It has largely been replaced by newer coagulants (CPD, Adsol) that allow for longer shelf life for blood and blood products. Acronym: ACD (05 Mar 2000) |
| acid deoxyribonuclease | An endonuclease that cleaves both strands of native DNA (as well as single-stranded DNA) to produce a mixture of oligodeoxynucleotides, each ending in a 3'-phosphate. Synonym: acid deoxyribonuclease. (05 Mar 2000) |
| acid dextran | The product of acid and heat treatment of dextran. (05 Mar 2000) |
