| blood sugar, high | Elevated levels of blood glucose (hyperglycaemia) can be found in a number of conditions. The hyperglycaemia leads to spillage of glucose into the urine, hence the term sweet urine. (Diabetes mellitus means sweet urine. ) (12 Dec 1998) |
|---|---|
| blood sugar, low | The sugar here is glucose. Low blood glucose constitutes hypoglycaemia. Hypoglycaemia is only significant when it is associated with symptoms. It has many causes including drugs, liver disease, surgical absence of the stomach, pre-diabetes, and rare tumours that release excess insulin. (12 Dec 1998) |
| malt sugar | <biochemistry> Disaccharide intermediate of the breakdown of starch, glucose _(1-4) glucose. Fermentable substrate in brewing. (20 Mar 1998) |
| gelatin sugar | <amino acid, physiology> The simplest amino acid. It is a common residue in proteins, especially collagen and elastin and is not optically active. It is also a major inhibitory neurotransmitter in spinal cord and brainstem of vertebrate central nervous system. (18 Nov 1997) |
| manna sugar | A medication given to reduce brain swelling and elevated intracranial pressure. Also used to temporarily disrupt the blood-brain barrier prior to some forms of chemotherapy. (16 Dec 1997) |
| maple sugar | Sucrose extracted from the sap of the sugar maple, Acer saccharinum. Synonym: saccharum canadense. (05 Mar 2000) |
| reducing sugar | A sugar, such as glucose in the urine, that has the property of reducing various inorganic ions, notably cupric ion to cuprous ion. (05 Mar 2000) |
| CDP-sugar | <abbreviation> Cytidine diphosphosugar. (05 Mar 2000) |
| pectin sugar | D-arabinose. See: arabinose. (05 Mar 2000) |
| 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) |
