The metabolism of circulating disaccharides was studied in adult humans and rats. After iv infusions of 10 g of either lactose, sucrose, or maltose in four adults, no rise in blood glucose was noted. A mean of 8.7±1.89 g of the lactose and 6.3±1.39 g of the sucrose was excreted in the 24-hour urine sample. Only 0.11±0.03 g of the infused maltose was recovered in the urine, suggesting that the maltose was metabolized.
