n. a soluble sugar, abundant in nature, that is a major source of energy for body tissues. The brain relies almost exclusively on glucose for its energy needs. Glucose is derived from the breakdown of carbohydrates, proteins, and—to a much lesser extent—fats. Its concentration in the bloodstream is tightly controlled by the opposing actions of the hormones insulin and glucagon. See also blood sugar.
