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
Thirty-two residues. In the real molecule the disulfide that closes salmon calcitonin is replaced by a carbon bridge, which the engine cannot draw, so the two cysteines are shown free here. Everything else is exact, and salmon calcitonin is in the library for comparison.

- Three-letter code
- Cys-Ser-Asn-Leu-Ser-Thr-Cys-Val-Leu-Gly-Lys-Leu-Ser-Gln-Glu-Leu-His-Lys-Leu-Gln-Thr-Tyr-Pro-Arg-Thr-Asn-Thr-Gly-Ser-Gly-Thr-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. Elcatonin is built from 14 of the twenty standard amino acids across 32 positions.
