| fructose-2,6-bisphosphate 6-phosphatase | <enzyme> Do not confuse with fructose-2,6-bisphosphate 2-phosphatase (EC 3.1.3.46) Registry number: EC 3.1.3.54 Synonym: fdp 6-phosphatase, fru(2,6)p2 6-phosphatase (26 Jun 1999) |

| fructose 6-phosphate | <biochemistry> A phosphorylated six-carbon sugar formed in the second step of glycolysis by the action of phosphoglucose isomerase on glucose-6-phosphate. In the third step, fructose 6-phospate and ATP are used to create fructose 1,6-biphosphate, ADP and a free hydrogen with the aid of phosphofructokinase. (08 Mar 2000) |
| fructose-6-phosphate phosphoketolase | <enzyme> Catalyses the conversion of d-fructose 6-phosphate and orthophosphate to acetylphosphate and d-erythrose 4-phosphate and water Registry number: EC 4.1.2.22 Synonym: f6p phosphoketolase (26 Jun 1999) |
| fructose-bisphosphatase | <enzyme> An enzyme that catalyses the conversion of d-fructose 1,6-bisphosphate and water to d-fructose 6-phosphate and orthophosphate. Chemical name: D-Fructose-1,6-bisphosphate 1-phosphohydrolase Registry number: EC 3.1.3.11 (12 Dec 1998) |
| fructose-bisphosphate aldolase | <enzyme> An enzyme of the lyase class that catalyses the cleavage of fructose 1,6-biphosphate to form dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. The enzyme also acts on (3s,4r)-ketose 1-phosphates. The yeast and bacterial enzymes are zinc proteins. (enzyme nomenclature, 1992) e.c. 4.1.2.13. Chemical name: D-Fructose-1,6-biphosphate D-glyceraldehyde-3-phosphate-lyase Registry number: EC 4.1.2.13 (12 Dec 1998) |
| fructose-diphosphate aldolase | <enzyme> An enzyme of the lyase class that catalyses the cleavage of fructose 1,6-biphosphate to form dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. The enzyme also acts on (3s,4r)-ketose 1-phosphates. The yeast and bacterial enzymes are zinc proteins. (enzyme nomenclature, 1992) e.c. 4.1.2.13. Chemical name: D-Fructose-1,6-biphosphate D-glyceraldehyde-3-phosphate-lyase Registry number: EC 4.1.2.13 (12 Dec 1998) |
| fructose intolerance | An autosomal recessive fructose metabolism disorder due to deficient fructose-1-phosphate aldolase (ec 2.1.2.13) activity, resulting in accumulation of fructose-1-phosphate. The accumulated fructose-1-phosphate inhibits glycogenolysis and gluconeogenesis, causing severe hypoglycaemia following ingestion of fructose. Prolonged fructose ingestion in infants leads ultimately to hepatic failure and death. Patients develop a strong distaste for sweet food, and avoid a chronic course of the disease by remaining on a fructose- and sucrose-free diet. (12 Dec 1998) |
| fructose metabolism, inborn errors | Inherited abnormalities of fructose metabolism, which include three known autosomal recessive types: hepatic fructokinase deficiency (essential fructosuria), hereditary fructose intolerance, and hereditary fructose-1,6-diphosphatase deficiency. Essential fructosuria is a benign asymptomatic metabolic disorder caused by deficiency in fructokinase, leading to decreased conversion of fructose to fructose-1-phosphate and alimentary hyperfructosaemia, but with no clinical dysfunction; may produce a false-positive diabetes test.

| fructose permease | <chemical> Fructose-specific enzyme II of phosphoenolpyruvate-dependent phosphotransferase system in e. Coli (26 Jun 1999) |
| active | Characterised by action, not passive, not expectant. (18 Nov 1997) |
| active acetate | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
| active aldehyde | Any aldehyde derivative of thiamin pyrophosphate. (05 Mar 2000) |
| active anaphylaxis | Reaction following inoculation of antigen in a subject previously sensitised to the specific antigen, in contrast to passive anaphylaxis. (05 Mar 2000) |
| active biomass | <cell biology> The amount of a given culture that is actively growing. (06 May 1997) |
| active carbon dioxide | Activated carbon dioxide, a complex of N-carboxybiotin (biotin + CO2) and an enzyme; the form in which carbon dioxide is added to other molecules in carboxylations; e.g., to methylcrotonyl-CoA to form beta-methylglutaconyl in the catabolism of leucine, and to acetyl-CoA to form malonyl-CoA. See: acetyl-CoA carboxylase. (05 Mar 2000) |
