Glucose (also called dextrose or cerelose) is 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 energy. Glucose is measured in routine blood and urine tests to detect diabetes.
The normal ranges for glucose are ...
- in blood after fasting overnight: 3.5 - 6 mmol/L
- in blood two hours after a meal: less than 8 mmol/L
- in urine: none
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.
