Most absorption of water and electrolytes occurs in the small intestine, with some water absorbed in the colon as well. However, it has been abandoned as a potential type 2 diabetes drug due to its rapid hydrolysis to phloretin, which inhibits facilitative GLUTs transporters present in various tissues [, Glucose absorption can be considered an integral part of the homeostatic system maintaining blood glucose levels, where it may provide the negative feedback to the brain control of food intake.

MDPI and/or The aim is to provide a snapshot of some of the Chan, L.K.Y. Differential responses of intestinal glucose transporter mRNA transcripts to levels of dietary sugars. Schwartz, M.W. Recent developments in the field of diabetes and obesity management have established the central role of the gut in glucose homeostasis; not only is the gut the primary absorptive site, but it also triggers neurohumoral feedback responses that regulate the pre- and post-absorptive phases of glucose metabolism. [Effects of different enteral nutrients on gut absorptive capacity and energy metabolism during gut ischemia/reperfusion]. Regul. Steady-state glucose absorption, obtained from data collected during the last 40 minutes of the perfusion period, was found to be significantly reduced in animals treated with drugs when intestinal absorption for control and treated animals was adjusted for water movement but not for dry intestinal weight and length. New insights in our knowledge of intestinal fructose absorption . The major route for the transport of dietary glucose from intestinal lumen into enterocytes is the Na + /glucose cotransporter (SGLT1), although glucose transporter type 2 (GLUT2) may also play a role. Disclaimer, National Library of Medicine CCK is responsible for exocrine pancreatic secretion, gallbladder contraction, and intestinal motility [, Leptin is a protein hormone secreted mainly by fat cells, but was also found within the gastric mucosa [, Considering the differences in luminal and plasma concentration of glucose, it appears that a fraction of glucose in the gut is not absorbed and hence can be metabolized by gut bacteria. For example, surgery and narcosis accompanying acute and chronic in vivo experiments significantly influence the levels and kinetics of nutrient hydrolysis and absorption in the small intestine [, Moreover, a quantitative evaluation of the relative contribution of different mechanisms of glucose absorption to the total glucose absorption may also depend on the method of calculation of the corresponding kinetic constants; in particular, whether the effects of the pre-epithelial diffusion layer and the peculiarities of the intestinal absorptive surface (presence of villi) are included in the calculations [, A slow (within 13 days) increase in glucose absorption, SGLT1 and its mRNA content in enterocytes were observed in several mammalian species in response to an increase of dietary carbohydrates [, It was shown that the adaptive response of glucose absorption by SGLT1 induced by an increase in carbohydrates in the diet (after 12 h), is first programmed in immature enterocytes localized in intestinal crypts. ; Srai, S.K. Sakar, Y.; Nazaret, C.; Lettron, P.; Ait Omar, A.; Avenati, M.; Viollet, B.; Ducroc, R.; Bado, A. The existence of a transport system on the basolateral membrane of enterocytes, which is inhibited by phloretin (phloridzin aglucon), was apparently first reported in 1976 by Kimmich and Randles [, At the end of the last century, Pappenheimer proposed that in natural conditions the glucose absorption at high glucose concentrations in the intestine occurs mainly through its paracellular transfer on the flow of absorbed water [, The hypothesis of the paracellular glucose transport was consistent with the data that the absorption of glucose in the small intestine is accompanied by an increase in water absorption [, The most weighty argument in favor of the paracellular glucose transport werevery high glucose concentrations in the lumen of the small intestine (up to 300500 mM) that supposedly exist in humans and animals after eating [, In our chronic experiments on rats at glucose concentrations in the lumen of the small intestine about 5075 mM, the paracellular transport of glucose on the flow of absorbed water was evaluated to be less than 15% of the total absorption of glucose [, A predominant transfer of glucose through the intestinal epithelium in the water flow (solvent entrainment) under the conditions of real digestion has not been supported by other studies [, Nevertheless, it should be noted that paracellular transport of substances is characterized by significant species differences. This suggests that the treatment of hyperglycemia based on SGLT1-mediated inhibition of small intestinal glucose absorption should be combined with other therapeutic strategies selectively targeting appetite control. J Dairy Sci. b, MeSH During high carbohydrate loading, paracellular transport with water flow and facilitated diffusion mediated by GLUT2 into the apical membrane of enterocytes further contribute to the total uptake of glucose. Bornet, F.R.J. Mechanisms of Glucose Absorption in the Small Intestine in Health and Metabolic Diseases and Their Role in Appetite Regulation. it is now generally accepted that in the range of relatively low concentrations of glucose (less than 30 mm) in the lumen of the small intestine, for example after eating a low-carbohydrate diet, the main route of absorption of this monosaccharide through the intestinal epithelium in vivo involves its active transport across the brush border L-Tryptophan Differentially Regulated Glucose and Amino Acid Transporters in the Small Intestine of Rat Challenged with Lipopolysaccharide. It zooms into the multiple villi on the small intestine and then continues to zoom into ta single epithelium cell where the process occurs. In fact, independent regulation of glucose absorption and appetite requires a more complex approach for the treatment of metabolic diseases. Mace, O.J. ; Greenway, F.L.

Multifaceted interplay among mediators and regulators of intestinal glucose absorption: Potential impacts on diabetes research and treatment. Positive regulatory control loop between gut leptin and intestinal GLUT2/GLUT5 transporters links to hepatic metabolic functions in rodents. We conclude that although inhibition of small intestinal glucose absorption represents a valuable target for the treatment of hyperglycemia, it is not always suitable for the treatment of hyperphagia. ; Lister, N.; Morgan, E.; Shepherd, E.; Affleck, J.; Helliwell, P.; Bronk, J.R.; Kellett, G.L.

Na(+)-D-glucose cotransporter SGLT1 is pivotal for intestinal glucose absorption and glucose-dependent incretin secretion. The review describes functions and regulations of SGLT1, GLUT2, and GLUT5 in the small intestine including diurnal variations and carbohydrate-dependent regulations. Changes in blood glucose levels are also involved in regulation of appetite, suggesting that glucose absorption may be relevant to hyperphagia in metabolic diseases. D-Glucose is an important fuel for the metabolic engines in the body and provides the main energy source for the critical activities of human life (Kowalski & Bruce, 2014; Zierler, 1999).D-Glucose is first absorbed through the small intestinal epithelial cells (IEC) and then transported to the bloodstream and its concentration in the blood is controlled by the combination of . 2021; 13(7):2474.

In fact, the role of glucose as a satiety factor in the short-term regulation of appetite is well-known and was the basis for glucostatic theory of appetite [, In recent years, various pathways of glucose transfer across the epithelium of the small intestine were studied concerning their contribution to the resultant absorption of glucose.

Early work by Anton Julius Carlson suggested that falls in blood glucose levels below post-absorptive levels may cause hunger, for example by inducing stomach hunger contractions [, Thus, intestinal glucose absorption does not seem to play a direct role in the short-term regulation of appetite, i.e., either in meal termination or its onset. Mayer, J. Glucostatic mechanism of regulation of food intake. Mechanisms of Glucose Absorption in the Small Intestine in Health and Hence, D-glucose absorption at low luminal glucose is mediated via SGLT1 in the BBM and GLUT2 in the BLM whereas high-capacity D-glucose absorption at high luminal glucose is mediated by SGLT1 plus GLUT2 in the BBM and GLUT2 in the BLM. https://www.mdpi.com/openaccess.
