Compound Relationship Map
Which peptides in the Research Library are analogues of, contained in, or other forms of each other, and which share a precursor, gene region or peptide family, each quoted from the compound record that states it.
35 stated relationships and 7 shared origins, across 13 families of records.
The map shows only what a compound record says in its own text, and quotes it. The build checks that every quotation still appears, word for word, in that record. Records can be related in other ways: each monograph lists its related compounds, and shared receptors are on the receptor map. Nothing here describes what any compound does.
- Analogue of
- A synthetic peptide the record describes as built on the parent's sequence.
- Sequence contained in
- Its residues appear within the longer chain; terminal groups can differ.
- Same chain, other form of
- Same residues with a different terminal group, acyl group or metal complex.
- Shared origin
- Records that each state the same precursor protein, gene region, gene family or peptide family.
