The Revolution in Insect Neuropeptides Illustrated by the Adipokinetic Hormone/Red Pigment-Concentrating Hormone Family of Peptides

Abstract

The last decade has seen a surge in the knowledge on primary structures of insect neuropeptides. Particularly successful were isolations and sequence determinations of more than 30 members of the adipokinetic hormone/red pigment-concentrating hormone (AKH/RPCH) family of peptides. This brief overview describes the techniques used to obtain data on purification and structure such as high performance liquid chromatography, Edman sequencing and mass spectrometry. Moreover, a short account on the precursors and on the multiple functions of the peptides of the AKH/RPCH family in various crustacean and insect species is given
