Crustacean Cardioactive Peptide (CCAP)

Crustacean Cardioactive Peptide (CCAP) is a highly conserved modified cyclic nonapeptide with a primary structure of PFCNAFTGC-NH2, a disulfide bridge between Cys3 and Cys9, which acts as a cardiac gas pedal, neuropeptide transmitter, and hormone with cardiac, adipotropic hormone, and metabolic regulatory effects, reproductive system.
