argireline

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

Six residues capped with an acetyl group at one end and an amide at the other, both of which are drawn. Modelled on the N-terminal end of a much larger protein involved in vesicle docking.

Sequence

Argireline amino-acid sequence in one-letter code, numbered by residue position
1EEMQRR
Three-letter code
Glu-Glu-Met-Gln-Arg-Arg

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. Argireline is built from 4 of the twenty standard amino acids across 6 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.
