glucose
Cellular energy currency
Glucose is a simple sugar that serves as the primary source of energy for living cells.
It circulates in the bloodstream and is the form of sugar that the body converts from carbohydrates during digestion.
When doctors measure blood sugar levels, they're measuring glucose; abnormal levels can indicate diabetes or other metabolic conditions.
In chemistry and nutrition, glucose is distinguished from other sugars like fructose and sucrose by its molecular structure.
