Alpha–conotoxin, omega–conotoxin and mu–conotoxin time–resolved absorption and resonance FT–IR and Raman biospectroscopy and density functional theory (DFT) investigation of vibronic–mode coupling structure in vibrational spectra analysis

International Journal of Advanced Chemistry, 2019
A Conotoxin is one of a group of neurotoxic peptides isolated from the venom of the marine cone snail, genus Conus. Conotoxins, which are peptides consisting of 10 to 30 amino acid residues, typically have one or more disulfide bonds. Conotoxins have a variety of mechanisms of actions, most of which have not been determined.
