Thus, following its transmembrane transportation, it is phosphorylated by hexokinase. The expression of hexokinase II in clear-cell RCC is elevated.[sup.40] Once FDG is phosphorylated, structural changes made by a hexose-phosphate bond prevent FDG from being catabolized or transported back into the extracellular space in substantial amounts.[sup.41] This "metabolic trapping" of FDG highlights the presence and location of RCC.
The StatStrip and the Advantage demonstrated the closest correlation with the plasma hexokinase reference method and demonstrated the lowest absolute bias.
The activities of hexokinase and pyruvate kinase were reduced while the activities of glucose-6-phosphatase and fructosel, 6-bisphosphatase were increased in rats fed high fructose.
Half of the class performs the glucose oxidase procedure and the other half performs the glucose hexokinase procedure.
The enzymatic conversion of nucleotide adenosine triphosphate (ATP) to adenosine diphosphate (ADP) by hexokinase was monitored in the bioreactor interfaced via the pneumatic sampler to a capillary electrophoresis unit [32].
The two specimens from San Fernando were identical at 14 of the 15 loci and differed only when stained for hexokinase (Table 2).
The tested enzymes were aconitase (ACO), acid phosphatase (ACP), alcohol dehydrogenase (ADH), adenylate kinase (AK), arginine aminopeptidase (AMP), diaphorase (DIA), endopetidase (EP), esterase (EST), fructose-1,6-diphosphatase (FDP), glutamate dehydrogenase (GDH), glutamate oxaloacetate transaminase (GOT), hexokinase (HK), isocitrate dehydrogenase (ICD), leucine aminopeptidase (LAP), malate dehydrogenase (MDH), malic enzyme (ME), peptidase with leucyl-alanine (PEP-LA), 6-phosphogluconate dehydrogenase (PGD), phosphoglucoisomerase (GPI), and shikimate dehydrogenase (SKDH) (Siciliano and Shaw, 1976; Vallejos, 1983; Van Geyt and Smed, 1984; Acquaah, 1992).
