Diffusion of glucose

Phloretin is the aglycon of phlorizin and inhibits the facilitated diffusion of glucose catalyzed by GLUT1 or GLUT4. It has been used to terminate the uptake of glucose in timed assays with isolated membranes or reconstituted transporters. 

Facilitated diffusion of glucose across the blood-brain barrier and into brain cells is catalyzed by GLUT1,- 2 and -3, products of the SLC2 gene superfamily 90... 

Figure 4.1 Schematic illustration showing encapsulation of a glucose sensor by host collagen and deterioration of the local microvessels adjacent to the implant. Fewer vessels deliver less glucose to the local tissue and the diffusion of glucose to the sensor is inhibited by the presence of the collagen capsule.

The facilitated diffusion of glucose into erythrocytes uses a mechanism called... 

Insulin stimulates glucose uptake into muscle and adipose cells, at least partly by translocating the glucose transporter (a membrane protein that carries out facilitated diffusion of glucose) from the cytosol (where it resides in the absence of insulin) to the cell surface, in response to insulin.
