Enzymic and Light-Induced Conversion of 5,6-Dihydroxyindole(s) to Melanin(s)

  • Giuseppe Prota


During the last two decades, whereas knowledge of the chemistry of phaeomelanins has been considerably added to, little progress has been made in the investigation of the structure and biosynthesis of eumelanins (Prota,1980). These pigments are of much greater biological interest since they are the major determinants of skin colour differences in man and are involved in a number of intriguing pigmentary phenomena, including sun tanning (Fitzpatrick et al.,1979).
