应用领域
多肽
胰高血糖素样肽是人体分泌的一种肠道激素,由胰高血糖素原(Proglucagon)分子经肠道蛋白水解酶作用而产生,因而称为胰高血糖素类多肽。胰高血糖素样肽-1是由30个氨基酸残基组成的多肽,肽链C端乙酰化;另一种为GLP-1(7-37),是由31个氨基酸残基组成的多肽。GLP-1(7-36)和GLP-1(7-37)有相同的促胰岛素分泌作用。研究表明当血糖浓度高于6mmol/L时,GLP-1能显著促进胰岛素分泌;而一旦血糖浓度恢复至正常值则不再继续作用,在临床上这一点对II型糖尿病的治疗十分有用。用途一
GLP-1 stimulates pancreatic β cells to secrete insulin as
an incretin hormone. GLP-1 also has additional actions,
including suppression of glucagon secretion, inhibition of
gastric motility, and promotion of satiety. GLP-1 was first identified in the early 1980s, following
the cloning of the proglucagon gene. The biological activity of GLP-1 was investigated initially by using the
N-terminal extended forms of GLP-1(1–37 and 1–36
amide). However, these forms were devoid of biological
activity. In the late 1980s, bioactive GLP-1 peptides were
purified from gut extracts and were identified to be GLP-1(7–37) and GLP-1(7–36)-amide. In the current literature,
the unqualified designation of GLP-1 corresponds to the
truncated peptides.参考质量标准
