1973年首先发现的生长抑素由14个氨基酸组成,环状排列,被称为14肽-生长抑素.较大分子前体的形式也随之被认识,为28肽-生长抑素,也称生长抑素原,其N端包括完整的14肽-生长抑素.前生长抑素原为含有120个氨基酸或更多氨基酸的多肽,其C端常含有28肽-生长抑素的排列顺序.14肽-生长抑素以药理剂量注入动物或人体内时,渐抑制许多内分泌和胃肠道的功能.虽然28肽-生长抑素的特异功能与14肽-生长抑素有所不同,但它也是
Somatostatin, first discovered in 1973, is composed of 14 amino acids arranged in a circular pattern called 14-peptide somatostatin, a form of larger molecule precursors that is also known as 28-somatostatin Said somatostatin, its N-terminal including the complete 14-peptide somatostatin.Pre-somatostatin is a peptide containing 120 amino acids or more amino acids, the C-terminal often contains 28 peptide - somatostatin arrangement order .14 Peptide-Somatostatin Inhibits Many Endocrine and Gastrointestinal Functions When Inject Pharmacologically into Animals or People Although the specific function of the 28-peptide somatostatin is different from that of 14-peptide somatostatin, it is also
