胰高糖素系胰岛A 细胞分泌的一种29肽的消化道激素,分子量3,845。最近国外研究人体内的胰高糖素部分来自肠高糖索,胰高糖素完整的分子结构存在于肠高糖素中,因此后者是胰高糖素的一个附加来源。胰高糖素除了能促进肝糖原分解,升高血糖外,还能抑制胃肠蠕动,降低胃、胰腺分泌盐类和酶,增加肝、胆汁和肠液的分泌,抑制肠粘膜对水、 Glucagon is a 29-peptide gut hormone secreted by pancreatic islet A cells with a molecular weight of 3,845. Recently, the part of glucagon in human body is derived from intestinal hyperglycemia. The intact molecular structure of glucagon exists in ghrelin, so the latter is an additional source of glucagon. Glucagon in addition to promoting hepatic glycogenolysis, increased blood sugar, but also inhibit gastrointestinal motility, reduce the stomach, the pancreas to secrete salt and enzyme, increase the secretion of liver, bile and intestinal fluid, inhibit the intestinal mucosa of water,
