Hvornår oplever kroppen den højeste glykogen rate?
Glycogen
Glykogen fungerer som en af to former for langsigtede energireserver, hvor den anden form er triglyceridlagrene i fedtvævet (dvs. kropsfedt). Hos mennesker dannes og lagres glykogen primært i cellerne i leveren og skeletmuskulaturen. I leveren kan glykogen udgøre 5-6 % af organets friskvægt, og leveren hos en voksen på 70 kg kan lagre ca. 100-120 g glykogen. I skeletmuskulaturen findes glykogen i en lav koncentration (1-2 % af muskelmassen), og skeletmuskulaturen hos en voksen på 70 kg lagrer ca. 400 g glykogen. Mængden af glykogen, der lagres i kroppen - især i musklerne og leveren - afhænger hovedsagelig af fysisk træning, basalstofskiftet og spisevaner. Der findes også små mængder glykogen i andre væv og celler, herunder nyrer, røde blodlegemer, hvide blodlegemer,[medicinsk citat nødvendigt] og gliaceller i hjernen. Livmoderen lagrer også glykogen under graviditeten for at give næring til embryoet.
Glycogen functions as one of two forms of long-term energy reserves, with the other form being triglyceride stores in adipose tissue (i.e., body fat). In humans, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the liver, glycogen can make up from 5–6% of the organ's fresh weight and the liver of an adult weighing 70 kg can store roughly 100–120 grams of glycogen. In skeletal muscle, glycogen is found in a low concentration (1–2% of the muscle mass) and the skeletal muscle of an adult weighing 70 kg stores roughly 400 grams of glycogen. The amount of glycogen stored in the body—particularly within the muscles and liver—mostly depends on physical training, basal metabolic rate, and eating habits. Small amounts of glycogen are also found in other tissues and cells, including the kidneys, red blood cells, white blood cells,[medical citation needed] and glial cells in the brain. The uterus also stores glycogen during pregnancy to nourish the embryo.
