[ COMPOUND.PROFILE ]

What Is Somatropin (HGH)?

Somatropin is recombinant human growth hormone (rhGH), a 191-amino acid single-chain polypeptide produced through recombinant DNA technology that is structurally and functionally identical to pituitary-derived human growth hormone. The protein adopts a four-helix bundle topology stabilized by two disulfide bonds (Cys53-Cys165 and Cys182-Cys189), and its biological activity is mediated through binding to the growth hormone receptor (GHR), a type I cytokine receptor expressed on hepatocytes, adipocytes, muscle cells, chondrocytes, and...
