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
Ten residues released from the beta chain of haemoglobin during digestion. Two shorter members of the same family are in the library.
Sequence
| 1 | LVVYPWTQRF |

- Three-letter code
- Leu-Val-Val-Tyr-Pro-Trp-Thr-Gln-Arg-Phe
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. Hemorphin-7 is built from 9 of the twenty standard amino acids across 10 positions.
