Sugar coupled to protein causes kidneys to save water
...e protein is not linked to a sugar, it still forms functional
water channels. However, these channels no longer end up at the cell surface where they need to do their work. Kidneys extract water containing dissolved waste substances from the blood. Each day human kidneys produced about 180 litres of this so-cal...
