Induces the release of nitric oxide. Other physiological functions include stimulation of pain receptors, inhibition of cAMP accumulation, and induction of smooth muscle contraction and vasodilation. Also involved in edema resulting from trauma or injury. Improves post-ischemic recovery of heart via a nitric oxide-dependent mechanism.Sequence:H-Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg-OHFormula:C50H73N15O11Solubility:5% acetic acid (1mg/ml)Molecular Weight:1060.2Storage and Stability:Lyophilized powder may be stored at -20°C.
