Peptide
A synthetic tetrapeptide of just four building blocks, as a crystalline solid. Best verified by identity, since its name is shared with a different substance.
Peptide
The copper-bound form of the tripeptide GHK: a single copper atom held by a three-building-block peptide, and a familiar small peptide in research.
Peptide
A synthetic 16-amino-acid peptide, unusual for being encoded within mitochondrial DNA rather than the nucleus. Supplied as a single-lot reference material.
Peptide
A defined 28-amino-acid peptide (thymalfasin) — the single-molecule counterpart to the thymus extract elsewhere in its collection. A crystalline solid.
