Glucokinase changes conformation and/or function in parallel with rising glucose concentrations in the physiologically important range of 4–10 M (72–180 mg/dL). It is half-saturated at a glucose concentration of about 8 mM (144 mg/dL). [10] [11] Glucokinase is not inhibited by physiological concentrations of its product, glucose-6-phosphate ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The glucokinase regulatory protein (GKRP) also known as glucokinase (hexokinase 4) regulator (GCKR) is a protein produced in hepatocytes (liver cells). GKRP binds and moves glucokinase (GK), thereby controlling both activity and intracellular location [1] [2] of this key enzyme of glucose metabolism. [3] GKRP is a 68 kD protein of 626 amino acids.
An oral glucose tolerance test is much less abnormal than would be expected from the impaired (elevated) fasting blood sugar, since insulin secretion is usually normal once the glucose has exceeded the threshold for that specific variant of the glucokinase enzyme. The degree of blood sugar elevation does not worsen rapidly with age, and long ...

For about 3 hours after a carbohydrate-containing meal, high insulin levels direct liver cells to take glucose from the blood, to convert it to glucose-6-phosphate (G6P) with the enzyme glucokinase and add the G6P molecules to the ends of chains of glycogen (glycogen synthesis).
