These are published properties of the molecule, given for identification. Values we cannot confirm are omitted rather than estimated. What these terms mean.
What this compound is
All 44 residues of human growth-hormone-releasing hormone with a trans-3-hexenoyl group on the N-terminal tyrosine, which is what blocks dipeptidyl peptidase cleavage. The largest structure in the set - modelled as an alpha helix.
Synthetic human GHRH(1-44) with a trans-3-hexenoic acid group on Tyr1.
Sequence
hexenoyl-YADAIFTNSYRKVLGQLSARKLLQDIMSRQQGESNQERGARARL-NH2
This sequence uses notation outside the standard twenty one-letter codes — a lowercase letter marks a D-amino acid, and other symbols mark modified or non-standard residues. It is reproduced exactly as published rather than normalised, and no residue composition is derived from it.
