1 Differences in glucagon-like peptide-1 and GIP responses following sucrose ingestion. Sucrose gastric inhibitory polypeptide Homo sapiens
2 To investigate the mechanism of oral carbohydrate-stimulated secretion of the two most potent incretin candidates, gastric inhibitory polypeptide (GIP) and truncated glucagon-like peptide-1 (tGLP-1), we studied the changes in the plasma levels of these peptides in five healthy men after sucrose ingestion with or without pretreatment with an alpha-D-glucosidase inhibitor (AO-128). Carbohydrates gastric inhibitory polypeptide Homo sapiens
3 After sucrose ingestion, plasma levels of GIP peaked at 15 min and remained high up to 120 min. Sucrose gastric inhibitory polypeptide Homo sapiens
4 After treatment with AO-128 (0.6 mg/day) for 1 week, increases in plasma glucose and insulin levels were attenuated and the increase in plasma GIP levels was diminished, while the increase in tGLP-1 levels was sustained much longer. AO 128 gastric inhibitory polypeptide Homo sapiens
5 It is concluded that GIP secretion is stimulated by glucose absorption and tGLP-1 secretion by the presence of sucrose in the gut. Glucose gastric inhibitory polypeptide Homo sapiens
6 It is concluded that GIP secretion is stimulated by glucose absorption and tGLP-1 secretion by the presence of sucrose in the gut. Sucrose gastric inhibitory polypeptide Homo sapiens
