Reading the catalog

Three structural classes.

Sorted by what each compound is, its molecular structure, not by outcome categories. Every listing is supplied for laboratory research use only.

Analog Peptides

A peptide whose sequence is a deliberate modification of a naturally occurring one, residues substituted, added, or chemically altered at defined positions.

Structurally related to a reference peptide, but not identical to it.

Peptide Fragments

A short, defined section of a longer native peptide or protein sequence, synthesised on its own rather than as part of the whole chain.

The sequence is native; the length is a subset.

Cofactors & Conjugates

Non-peptide molecules, and peptides bound to a non-peptide partner such as a metal ion or small molecule.

Defined by what the molecule is joined to, not by chain length.
