Document Summary

Monosaccharides are absorbed by the small intestine then transported to the blood. Glucose distributed to the body"s cells for fuel. Fructose and galactose taken up by liver and converted to glucose: exported to blood. The storage form of glucose for animals (including humans) We store glycogen in our muscles and liver and we can break it down very quickly when we need it for energy. Storing glucose as glycogen (holds water: liver storage (about 1/3) Hydrolysis for release of glucose when needed: muscle storage. The monosaccharides are transported through the bloodstream to the liver where they are converted to glucose. Based on need, the liver releases glucose into the bloodstream or stores it as glycogen. The liver can store 70 grams of glycogen and muscles can store 120 grams of glycogen. Between meals, the body draws on liver glycogen reserves to maintain blood glucose levels and support needs of cells including the brain, spinal cord and red blood cells.
