Another group of minor active peptides are the virotoxins, which consist of six similar monocyclic heptapeptides.

Honeybee venom: A rich source of pharmacologically active peptides.

Recently, several biologically active peptides called cliotides have been isolated from the heat-stable fraction of Clitoria ternatea extract.

In common with most active peptides, both hormones are synthesised as larger protein precursors that are enzymatically converted to their mature forms.

Granins may serve as precursors for biologically active peptides.

CRH is evolutionary related to a number of other active peptides.

Cortistatin-17 is the only active peptide derived from the precursor.

The precursors to HypSys are processed into more than one active peptide.

Like many other active peptides they are synthesized as larger protein precursors that are enzymatically converted to their mature forms.

The characterization of over 50 biologically active peptides from the snail's venom had been made possible, in part, by her studies.
