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
Seven residues with a D-alanine at position two, mirrored here. One of the most receptor-selective opioid peptides known, and the selectivity comes almost entirely from that one inverted residue.
Sequence
YaFDVVG
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.
