GH Secretagogues
HGH (Human Growth Hormone, Somatropin)
Scientific Profile
Human Growth Hormone (Somatropin) is a 191-amino acid single-chain polypeptide with two disulfide bridges. Recombinant HGH produced in E. coli demonstrates identical amino acid sequence and biological activity to native pituitary GH.
In vitro studies confirm its ability to bind GH receptors, activating JAK2-STAT5 signaling pathways. The protein exhibits specific conformational requirements for receptor interaction, with the third alpha-helix being particularly crucial for biological activity in experimental models.
