<unk>  is a term used to refer to the amount of glucose in the blood. Glucose, transported via the bloodstream, is the primary source of energy for the body's cells.<unk>  concentration, or glucose level, is tightly regulated in the human body. Normally, the blood glucose level is maintained between about 4 and 8 mmol/L (70 to 150 mg/dL). The total amount of glucose in the circulating blood is therefore about 3.3 to 7g (assuming an ordinary adult blood volume of 5 liters). Glucose levels rise after meals and are usually lowest in the morning, before the first meal of the day.
Failure to maintain blood glucose in the normal range leads to conditions of persistently high (hyperglycemia) or low (hypoglycemia)<unk> . Diabetes mellitus, characterized by persistent hyperglycemia of several causes, is the most prominent disease related to failure of<unk>  regulation.
Though it is called<unk> " and<unk> s besides glucose are found in the blood, like fructose and galactose, only glucose levels are regulated via insulin and glucagon.
