| 产品名称: | Ghrelin Peptide |
| 产品链接: | http://www.abbiotec.com/peptides/ghrelin-peptide |
| 货号: | 350193 |
| 规格: | 1 mg |
| 产品描述: | Ghrelin (also called Ghrelin-28) is the ligand for growth hormone secretagogue receptor type 1 (GHSR). Ghrelin induces the release of growth hormone from the pituitary gland. Ghrelin has an appetite-stimulating effect, induces adiposity and stimulates gastric acid secretion. The 117-aa Ghrelin precursor, the growth hormone-releasing peptide (GHRP), is cleaved into 3 chains: Ghrelin-27 (27 aa), Ghrelin-28 (28 aa) and obestatin (23 aa). Ghrelin-28 is a 28-aa peptide modified by O-octanoylation or O-decanoylation essential for activity. The O-decanoylated forms Ghrelin-27-C10 and Ghrelin-28-C10 differ in the length of the carbon backbone of the carboxylic acid bound to Ser-26. Cat. No. 350193 corresponds to the Ghrelin-28-C8 form. |
| 序列: | Human: H-Gly-Ser-Ser(octanoyl)-Phe-Leu-Ser-Pro-Glu-His-Gln-Arg-Val-Gln-Gln-Arg-Lys-Glu-Ser-Lys-Lys-Pro-Pro-Ala-Lys-Leu-Gln-Pro-Arg-OH or H-GSS(octanoyl)FLSPEHQRVQQRKESKKPPAKLQPR-OH |

文献和实验二个以上的α -氨基酸以肽键连接起来而形成的化合物。根据构成氨基酸的数目 2、 3、 4……叫做二肽( dipeptide)、三肽、四肽……。大体上由 10以下的肽键形成的肽总称为寡肽 ( Oligopeptide),由多数肽键构成的肽总称为多肽。每个肽按照构成它的氨基酸的名称,从具有游离α -氨基的末端氨基酸依次命名。例如 称为甘氨酰丙氨酸的二肽。蛋白质是由一条或几条长链状多肽构成的。象谷胱甘肽和肌肽那样的低
科学家在二○○○年稍早发现 ghrelin 主要是由老鼠及人的胃部细胞所分泌,下视丘也有少量的表现,和前两个摄食调控信号产生的方式不同。Ghrelin 是由 28 个氨基酸所构成,在身体里面的作用是促进脑下垂体生长激素的释放,同时也会强力地刺激食欲而引起进食。 研究显示将 ghrelin 注射到老鼠的腹腔或脑室中,会使得脂肪的分解减少而导致体重增加。ghrelin 注射到老鼠脑室中也会增加老鼠的摄食量及体重,且随着 ghrelin 注射量增加,效果就愈显著。老鼠在禁食状态
