Ball-and-stick model of a glucose molecule. Blood sugar regulation is the process by which the levels of blood sugar, the common name for glucose dissolved in blood plasma, are maintained by the body within a narrow range. The regulation of glucose levels through Homeostasis. This tight regulation is referred to as glucose homeostasis.
Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. [2] Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas. [2] Once inside the cell, the glucose can now act as an energy source as it undergoes the process of glycolysis.
Glucose-containing compounds are digested and taken up by the body in the intestines, including starch, glycogen, disaccharides and as monosaccharide. Glucose is stored in mainly the liver and muscles as glycogen. It is distributed and utilized in tissues as free glucose. To discuss image, please see Template talk:Human body diagrams
Glucose circulates in the blood of animals as blood sugar. [5] [7] The naturally occurring form is d-glucose, while its stereoisomer l-glucose is produced synthetically in comparatively small amounts and is less biologically active. [7] Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose ...
d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...
Glucose-6-phosphate can then progress through glycolysis. [1] Glycolysis only requires the input of one molecule of ATP when the glucose originates in glycogen. [1] Alternatively, glucose-6-phosphate can be converted back into glucose in the liver and the kidneys, allowing it to raise blood glucose levels if necessary. [2]

The destruction of these cells reduces the body's ability to respond to glucose levels in the body, therefore making it nearly impossible to properly regulate glucose and glucagon levels in the bloodstream. [25] The body destroys 70–80% of beta cells, leaving only 20–30% of functioning cells.
