cómo se transporta la glucosa través de la membrana celular? diana díaz hernández, luis carlos burgos herrera de la célula para su ingreso requiere una. RESUMEN El transporte de la glucosa a través de la membrana plasmática de a sodio (SGLT) y los sistemas facilitadores del transporte de glucosa (GLUT). Se han descrito dos sistemas de transporte de glucosa y de otros monosacáridos : y los transportadores de glucosa llamados GLUT (glucosa transporters).

All three monosaccharides glucosegalactoseand fructose are transported from the intestinal mucosal cell into the portal circulation by GLUT2. Cloning and functional expresssion in bacteria of a novel glucose transporter present in liver, intestine, kidney, and B-pancreatic islet cells. These studies have revealed that, in DM2, the GLUT4 content is drastically reduced, playing an important role in insulin resistance.

In Saccharomyces cerevisiae glucose transport takes place through facilitated diffusion. Horm Metab Res ; In the adult, it is expressed at highest levels in erythrocytes and also in the endothelial cells of barrier tissues such as the blood—brain barrier.
