 Definition: 
  1. Glucose is measured in venous blood and urine samples to detect diabetes mellitus or latent diabetes.

    Normal Ranges:

    fasting blood glucose: 3.5 - 6 mmol/L
    2 hours after a meal (postprandial): less than 8 mmol/L
    urinary glucose: negative

  2. A six-carbon monosaccharide which is the major sugar in the blood and is an important intermediate molecule in metabolic processes. It is often given intravenously to replenish fluids and provide nutrients.

    In glycolysis, all six-carbon intermediates are derived from glucose and fructose. In the first step of glycolysis, hexokinase catalyzes the conversion of glucose and ATP into glucose 6-phosphate. Also, in the conversion of one molecule of glucose into two molecules of pyruvate, two molecules of ATP are also generated.
