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
Eight residues opening with a pyroglutamate ring. Structurally related to neurotensin, which is also here, sharing its hydrophobic tail.
Sequence
2GKRPWIL
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.
