The average Western adult metabolizes hundreds of grams of carbohydrates per day, half of which is used as an energy source for the brain. To benefit from these ingested carbohydrates, they must first be broken down into simple sugars, such as glucose, and absorbed through the epithelial cells of the intestine. The glucose must then be reabsorbed in the kidneys. On page 810 of this issue, Faham et al.(1) report a major advance in elucidating the molecular mechanism by which this highly effective absorption is realized.Glucose is absorbed from the lumen into the epithelial cell by the Na+/glucose cotransporter SGLT1 in the intestine and by the related SGLT2 in the kidney (see the figure). The glucose is then exported by the glucose transporter GLUT2 to the basal side of the cell into the blood. These transport proteins share the same substrate and all function as so-called secondary membrane transporters, but they are members of distinct protein families: SGLT1 and SGLT2 are solute sodium symporters (SSS),
