甘丙肽是Ｔａｔｅｍｏｔｏ于 83年从猪小肠提取物中发现的一种 2 9肽 ,其Ｎ和Ｃ端分别为甘氨酸和丙氨酸残基。研究表明 ,甘丙肽广泛分布于中枢和外周组织 ,具有调节胃肠平滑肌收缩、抑制胰岛素分泌、加强吗啡镇痛效应和参与记忆等功能 ,尤其在损伤组织的修复过程中发挥了重要作 Galanin is a 2 9 peptide discovered by Tatemoto from pig intestine extracts in 83, with glycine and alanine residues at the N and C termini, respectively. Studies have shown that galanin widely distributed in the central and peripheral tissues, with regulation of gastrointestinal smooth muscle contraction, inhibition of insulin secretion, strengthening morphine analgesic effect and participation in memory and other functions, especially in the repair process of injured tissue has played an important role
