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

Sixteen residues from the tail end of human growth hormone. Two cysteines are present; in the parent protein they form a disulfide, and this model draws them free because the isolated fragment is usually handled in reduced form.

Sequence

HGH Fragment 176-191 amino-acid sequence in one-letter code, numbered by residue position
1YLRIVQCRSV EGSCGF
Three-letter code
Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-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. HGH Fragment 176-191 is built from 11 of the twenty standard amino acids across 16 positions.

Side-chain classes follow the standard grouping of the twenty proteinogenic amino acids. Composition is arithmetic over the published sequence and says nothing about how the molecule behaves.
