“…These markedly different results cannot be ascribed to techniques of sugar analysis (2) of lactose intolerance in a patient who had a normal blood sugar rise after the ingestion of sucrose even though the ileum had been surgically removed 3 months previously. Thus it appears that the site of absorption of sucrose is no different from that of other disaccharides (1,25) and monosaccharides (26)(27)(28).…”

Sucrose, unlike the other common disaccharides, maltose and lactose, has been reported to be absorbed poorly from jejunum in man. The present studies were designed to examine further the absorption of sucrose in normal man. MethodsTwenty-three normal young adults (21 males, 2 females) were studied on 50 occasions. A double-lumen polyvinyl tube with a small, terminal, mercury-filled balloon (6) was swallowed the evening before the study and allowed to move into the small intestine overnight. Subjects were permitted to have a supper containing clear liquids on the day before the study, but they ingested nothing but water for the 12-hour period before begining the experiment. One lumen of the tube was used to collect intestinal samples through an orifice placed just proximal to the terminal balloon. The other lumen, through which the test solution was infused, had its opening 30 cm proximal to the collecting orifice. Position of the tube was checked fluoroscopically before the study, and any coiling in the stomach was removed. When the collecting orifice was a distance of 60 to 100 cm from the incisor teeth, it was found fluoroscopically to be in the duodenum, when 100 to 170 cm in the jejunum, and when 170 to 260 cm in the ileum. At distances exceeding 260 cm, the distal orifice of the tube was often found to be in the colon. These relationships are similar to those previously reported (1,(6)(7)(8)

“…It is also necessary to consider the mechanism concerned in the absorption of glucose and galactose which is believed to be shared between them. There is some evidence that galactose is preferentially absorbed when equimolecular solutions of glucose and galactose are given together (Groen, 1937). From the gradients in Table 2 it can be seen that the values for the glucose and galactose mixture are about the same as those for galactose, whereas one might expect the value for the mixture to lie half way between the values for its constituents separately.…”

“…It is recognized that the intestinal absorption of fructose is slower than glucose (18,19) and that differences in absorption rates among individuals with varying disease states may also exist. Intravenous tolerance tests, therefore, were employed to facilitate comparison of the rates of utilization.…”
