| grape sugar | See: d-glucose. Invert sugar, a mixture of equal parts of d-glucose and d-fructose produced by hydrolysis of sucrose (inversion). (05 Mar 2000) |
| phosphoenolpyruvate sugar phosphotransferase system | <enzyme> The bacterial sugar phosphotransferase system (pts) that catalyses the transfer of the phosphoryl group from phosphoenolpyruvate to its sugar substrates (the pts sugars) concomitant with the translocation of these sugars across the bacterial membrane. The phosphorylation of a given sugar requires four proteins, two general proteins, enzyme I and hpr and a pair of sugar-specific proteins designated as the enzyme II complex. The pts has also been implicated in the induction of synthesis of some catabolic enzyme systems required for the utilization of sugars that are not substrates of the pts as well as the regulation of the activity of adenylate cyclase. Registry number: EC 2.7.1.- (12 Dec 1998) |
| milk sugar | A disaccharide present in mammalian milk, used in infant formulas, large doses can act as a laxative. (27 Sep 1997) |
| wood sugar | D-xylose. See: xylose. (05 Mar 2000) |
| protein-N-pi-phosphohistidine - sugar phosphotransferase | <enzyme> Enzyme II of the system; leve is the the IIb subunit from bacillus subtilis Registry number: EC 2.7.1.69 Synonym: phph-phosphotransferase, phosphohistidinoprotein-hexose phosphotransferase, leve gene product, IIb(lev) (26 Jun 1999) |
| specific soluble sugar | A soluble type-specific polysaccharide produced during active growth of virulent pneumococci composing a large part of the capsule. Synonym: pneumococcal polysaccharide, soluble specific substance, specific soluble polysaccharide, specific soluble sugar. (05 Mar 2000) |
| starch sugar | See: d-glucose. (05 Mar 2000) |
| sugar | <biochemistry, chemistry> Common name for any sweet, crystalline, simple carbohydrate which is an aldehyde or ketone derivative of a polyhydric alcohol. Sugars are mainly disaccharides like sucrose and monosaccharides like fructose, all are soluble indilute alcohol or water and are white in their pure form. (09 Oct 1997) |
| sugar acids | Acids, such as gluconic, glycuronic, and saccharic acid, produced by the oxidation of glucose. (05 Mar 2000) |
