Dipeptide absorption in man.
A quantitative perfusion method has been used to study intestinal absorption of two dipeptides-glycyl-glycine and glycyl-l-alanine-in normal subjects. In each case, the constituent amino acids were absorbed faster when presented as dipeptides than as free amino acids, suggesting intact dipeptide transport. During absorption constituent amino acids were measured within the lumen and it is sugges...
متن کاملFerritin iron absorption in man.
The iron absorption from ferritin and hemosiderin biosynthetically labeled with radioiron was studied in 108 subjects. The geometric mean absorption of ferritin iron in both normal and iron-deficient subjects was 1.9 percent. Its mean absorption ranged from 0.9 percent in normal subjects to 2.5 percent in subjects with moderate iron deficiency and 5.7 percent in subjects with marked iron defici...
متن کاملAbsorption of carotene in man.
According to the report of the national nutritional survey performed by the Ministry of Health and Welfare, over 90 per cent of source for vitamin A of the Japanese is provltamin A, especially, ƒÀ-carotene. It is therefore an impor tant problem to know the absorbability of carotene by the Japanese for estab lishing the dietary allowance of vitamin A for the nation. Though a number of studies co...
متن کاملGlucose-dependent insulinotropic polypeptide regulates dipeptide absorption in mouse jejunum.
Glucose-dependent insulinotropic polypeptide (GIP) secreted from jejunal mucosal K cells augments insulin secretion and plays a critical role in the pathogenesis of obesity and Type 2 diabetes mellitus. In recent studies, we have shown GIP directly activates Na-glucose cotransporter-1 (SGLT1) and enhances glucose absorption in mouse jejunum. It is not known whether GIP would also regulate other...
متن کاملAbsorption of dietary cholesterol in man.
Cholesterol absorption was studied by balance methods in 10 hyper!ipemic subjects. The cholesterol (401-1214 mg/day) and j:?-sitosterol (171-454 mg/ day) were integral parts of the diets. The absorption was 37% :±: 5% and the amounts of cholesterol absorbed were 149-508 mg/day. The amounts absorbed had an excellent correlation with the dietary intake of cholesterol {r = 0.98), and there was no ...
