Electrochemical and Spectroscopic Study of Peptide-template Melanins
, 2018 Melanins are organic polymers made up of 5,6-dihydroxyindole carboxylic acid (DHICA) and 5,6-dihydroxyindole (DHI). Biochemical systems synthesize melanins through a complex reaction pathway. Previous research exhibited that naturally-occurring melanins (

SPECTROSCOPIC FEATURES OF NATIVE AND BLEACHED OPIO-MELANINS
, 1995 Opioid peptides can be converted by tyrosinase into melanin-like compounds, in which the peptide moiety is retained. Such pigments, named opio-melanins, exhibit a characteristic absorption spectrum with a maximum at about 330 nm and a different ...
