Furthermore, several congenital defects of sugar metabolism are caused by aberrant transporter genes (eg, the glucose-galactose malabsorption syndrome, SGLT1; the glucose transporter 1 deficiency syndrome; and the Fanconi-Bickel syndrome, GLUT2).
Because the lipid bilayer of the eucaryotic plasma membrane is impermeable for hydrophilic molecules, glucose is transported across the plasma membrane by membrane associated carrier proteins, glucose transporters.
The sodium-dependent glucose transporters, also known as co-transporters or symporters, are integral membrane proteins that mediate the transport of glucose and, with much lower affinity, galactose across the plasma membrane by an active transport mechanism.15 This transport process is a cotransport of glucose molecules and sodium ions.

 Glucose transporter - Wikipedia, the free encyclopedia
Glucose transporters (GLUT or SLC2A family) are a family of membrane proteins found in most mammalian cells.
Transport of glucose through the apical membrane of intestinal and kidney epithelial cells depends on the presence of secondary active Na+/glucose symporters, SGLT-1 and SGLT-2, which concentrate glucose inside the cells, using the energy provided by cotransport of Na+ ions down their electrochemical gradient.
Facilitated diffusion of glucose through the cellular membrane is otherwise catalyzed by glucose carriers (protein symbol GLUT, gene symbol SLC2 for Solute Carrier Family 2) that belong to a superfamily of transport facilitators (major facilitator superfamily) including organic anion and cation transporters, yeast hexose transporter, plant hexose/proton symporters, and bacterial sugar/proton symporters.

 InterPro: IPR000803 Facilitated glucose transporter   (Site not responding. Last check: 2007-10-13)
The ability to transport glucose across the plasma membrane is a feature common to nearly all cells, from simple bacteria through to highly specialised mammalian neurones.
Facilitative sugar transport is mediated by members of the GLUT transporter family, which form an aqueous pore across the membrane through which sugars can move in a passive (i.e., energy-independent) manner; in consequence, they can only transport sugars down their concentration gradient.
In the GLUT transporters, this motif is present in the presumed cytoplasmic loops connecting TM domains 2 with 3, and also 8 with 9.

 InterPro: IPR005828 General substrate transporter
Recent genome-sequencing data and a wealth of biochemical and molecular genetic investigations have revealed the occurrence of dozens of families of primary and secondary transporters.
While ABC family permeases are in general multicomponent primary active transporters, capable of transporting both small molecules and macromolecules in response to ATP hydrolysis the MFS transporters are single-polypeptide secondary carriers capable only of transporting small solutes in response to chemiosmotic ion gradients.
Although well over 100 families of transporters have now been recognized and classified, the ABC superfamily and MFS account for nearly half of the solute transporters encoded within the genomes of microorganisms.
