Crustacean cardioactive peptide, Cyclic

Crustacean Cardioactive Peptide (CCAP) is a cyclic, C-terminally amidated nonapeptide originally identified in Manduca sexta. It serves as a crucial cardioregulatory and neurohormonal factor in insects, enabling in vivo and in vitro research into cardioactivity, ecdysis behavior, and neuronal signaling.
