1.Studies on absorption and metabolism of palatinose (isomaltulose) in rats.
Tonouchi H1, Yamaji T, Uchida M, Koganei M, Sasayama A, Kaneko T, Urita Y, Okuno M, Suzuki K, Kashimura J, Sasaki H. Br J Nutr. 2011 Jan;105(1):10-4. doi: 10.1017/S0007114510003193.
We evaluated the absorption and metabolism of palatinose in rats by the carbohydrate load test and the 13C- and H2-breath tests. We compared the results of these tests with those of sucrose, since sucrose is an isomer of palatinose and generally known to be degraded and absorbed from the small intestine. In the carbohydrate load test, blood glucose and plasma insulin levels after oral administration of palatinose rose more gradually and reached a maximum that was lower than that after sucrose administration. In the 13C-breath test, rats were orally administrated [1-13C]sucrose or [1-13C]palatinose and housed in a chamber. The expired air in the chamber was collected, and the level of 13CO2 in the expired air was measured at appropriate intervals for 360 min. The value of time taken to reach the maximum concentration for expired 13CO2 from [1-13Cglucose] ([1-13Cglc]) and [1-13Cfructose] ([1-13Cfru]) palatinose was significantly longer than that from [1-13Cglc] and [1-13Cfru]sucrose, respectively.
