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
Nine residues. Exactly the alpha form with the terminal lysine removed, which is a single trimming step, and both are here to show it.
Sequence

- Three-letter code
- Tyr-Gly-Gly-Phe-Leu-Arg-Lys-Tyr-Pro
The one-letter code gives the amino-acid backbone. Terminal modifications, where a compound carries them, are accounted for in the molecular weight above but are not visible in the letters.
Residue composition
Counted directly from the sequence above. Beta-neoendorphin is built from 7 of the twenty standard amino acids across 9 positions.
