Glucose Absorption

Glucose absorption refers to the process by which glucose, a primary energy source, is transported from the lumen of the small intestine into enterocytes (intestinal epithelial cells) and then into the bloodstream. This process is essential for providing energy to body tissues and maintaining blood glucose homeostasis. The main mechanism involves SGLT1 (Sodium-Glucose Linked Transporter 1) for active transport and GLUT2 (Glucose Transporter Type 2) for facilitated diffusion. Regulation involves membrane potential and intracellular calcium levels. Defects can result in malabsorption syndromes, while modulation has therapeutic potential for obesity and diabetes.
