HUMAN NUTRITION

Detailed explanation-1: -Glycogen is the storage form of carbohydrates in mammals. In humans the majority of glycogen is stored in skeletal muscles (∼500 g) and the liver (∼100 g). Food is supplied in larger meals, but the blood glucose concentration has to be kept within narrow limits to survive and stay healthy.

Detailed explanation-2: -When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-3: -Glycogen is a ubiquitous fuel source stored in the cytosol of cells, occupying 2% of the volume of cardiac cells, 10 1%–2% of the volume of skeletal muscle cells, and 5%–6% of the volume of liver cells.

Detailed explanation-4: -Excess carbohydrates are converted into sugars like glycogen and stored in the body. Thus, glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesised and stored mainly in the liver and the muscles.

Detailed explanation-5: -Carbohydrates are also stored in the tissue as glycogen for use in the production of energy, when necessary. Glycogen is the stored fuel particularly in tissues such as skeletal muscles which then have to work with a supply of oxygen far lower than their immediate need.
