17 Οκτ 2022 · Function. Fructose promotes the uptake and storage of glucose in the liver. Fructose also helps to speed up the oxidation of carbohydrate stores after a meal. Fructose provides the majority of the energy required for the mobility of spermatozoa. Seminal vesicles are responsible for the secretion of fructose.
Fructose digestion and absorption in humans. Fructose exists in foods either as a monosaccharide (free fructose) or as a unit of a disaccharide (sucrose). Free fructose is a ketonic simple sugar and one of the three dietary monosaccharides absorbed directly by the intestine.
5 Ιουλ 2024 · Learn how fructose is transported, phosphorylated, and cleaved by enzymes in the liver, and how it affects energy production and lipid biosynthesis. Explore the differences and similarities between fructose and glucose metabolism, and the implications for health.
Fructose accelerates carbohydrate oxidation after a meal. In addition, emerging evidence suggests that fructose may also play a role in the secretion of insulin and GLP-1, and in the maturation of preadipocytes to increase fat storage capacity.
6 Οκτ 2021 · In this review, Herman and Birnbaum discuss the biochemistry, genetics, and physiology of fructose metabolism, consider mechanisms by which excessive fructose consumption contributes to disease, and review recent evidence regarding the potential for new therapeutic agents.
This article reviews the properties and sources of fructose in the food supply, the estimated intake of fructose in Western diets, the intestinal absorption of fructose, and the metabolism of fructose and its effect on lipid and glucose metabolism.
17 Οκτ 2019 · Specifically, fructose is metabolized by fructokinase C (KHK-C) in various tissues including the intestine, liver, kidney, islets, adipose tissue and brain, where it causes a rapid phosphorylation of fructose to fructose-1-phosphate.
