Fibrinopeptide A, human acetate (Humanfibrinopeptide A acetate)(25422-31-5 free base) 是一种 16 个残基的短多肽,由凝血酶从纤维蛋白原上切割下来。纤维蛋白肽 A (FPA) 由纤维蛋白原蛋白的 N 末端 Aα 区域在被凝血酶切割后产生。
Fibrinopeptide A, human is a 16-residue short polypeptide cleaved from fibrinogen by thrombin. Fibrinopeptide A, human locates at the NH2-termini of the Aα chain.The conversion of monomeric fibrinogen into polymeric fibrin is mediated by thrombin, which b
[Glu1]-Fibrinopeptide B, a derivative of fibrinopeptide B amino acid residues 1-14, originates from humanfibrinopeptide B (hFpB). hFpB is a proteolytic cleavage product of the fibrinogen B beta-chain, specifically generated by thrombin, which plays a significant role in activating neutrophils (PMN), monocytes, and fibroblasts.
Orexin B, human, is an endogenous agonist at Orexin receptors with Ki values of 420 nM for OX1 and 36 nM for OX2, respectively. Orexin B is a hypothalamic neuropeptide that stimulates food intake in rats.
Highly potent and selective OX2 receptor agonist; displays 400-fold selectivity over OX1 receptors. EC50 values are 0.13 and 52 nM for human OX2 and OX1 receptors respectively.
