| alkaline | <chemistry> Having the reactions of an alkali. Origin: L. Alkalinus (18 Nov 1997) |
|---|---|
| alkaline-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) |
| alkaline D-peptidase | <enzyme> A penicillin-recognizing enzyme from bacillus cereus; has beta-lactamase activity; genbank d86380 Registry number: EC 3.4.99.- Synonym: ADP gene product, alkaline d-stereospecific endopeptidase (26 Jun 1999) |
| alkaline earth | <chemistry> Any of the metallic elements found in the second column of the periodic table, such as calcium and magnesium. (09 Oct 1997) |
| alkaline earth elements | Those element's in the family Be, Mg, Ca, Sr, Ba, and Ra, the hydroxides of which are highly ionised and hence alkaline in water solution. (05 Mar 2000) |
| alkaline earths | See: alkaline earth elements. (05 Mar 2000) |
| alkaline elastase | <enzyme> Serine proteinase with molecular weight of 25,000 from alkalophilic bacillus sp. Ya-b Registry number: EC 3.4.21.- (26 Jun 1999) |
| alkaline milk drip | A variable mixture of sodium bicarbonate in whole milk dripped into the stomach through a small oral or nasal tube to produce constant achlorhydria; used in the treatment of certain ulcers. (05 Mar 2000) |
| alkaline phosphatase | <enzyme> An enzyme that catalyses the cleavage of inorganic phosphate non-specifically from a wide variety of phosphate esters and having a high (greater than 8) pH optimum. Found in bacteria, fungi and animals but not in higher plants. (18 Nov 1997) |
| alkaline protease | <enzyme> These proteases work best in the pH range of 8 to 11 and are used widelyin washing powders and to de-hair hides. Alkaline proteases are mainlyproduced by bacteria in the Bacillus species. (13 Nov 1997) |
| alkaline reaction | Any test by which an alkaline reaction is recognised, such as the change of red litmus paper to blue, an excess of hydroxide ions over hydrogen ions in aqueous solution as indicated by a pH value greater than 7 (at 22캜). Compare: dissociation constant of water. Synonym: basic reaction. (05 Mar 2000) |
| alkaline reflux gastritis | An inflammation of the gastric mucosa believed to be caused by irritating factors in bile. Synonym: alkaline reflux gastritis. (05 Mar 2000) |
| alkaline tide | A period of urinary neutrality or even alkalinity after meals due to withdrawal of hydrogen ion for the purpose of secretion of the highly acid gastric juice. Synonym: alkaline wave. (05 Mar 2000) |
| alkaline water | A water that contains appreciable amounts of the bicarbonates of calcium, lithium, potassium, or sodium. (05 Mar 2000) |
| alkaline wave | A period of urinary neutrality or even alkalinity after meals due to withdrawal of hydrogen ion for the purpose of secretion of the highly acid gastric juice. Synonym: alkaline wave. (05 Mar 2000) |
