A review focuses on the pigments derived biogenetically from tyrosine and produced intracellularly within specialized cells. Melanin pigments, eumelanins and pheomelanins, can be described today as collections of mol. species with different chem. structures and properties, thus encompassing diverse degrees of chem. heterogeneity. This mol. heterogeneity can be ascribed to a no. of factors, including the range of different monomer units; the different mdes of inter-unit coupling; differences in mol. wt.; the redox state; and the extent and mode of aggregation

Abstract
A review focuses on the pigments derived biogenetically from tyrosine and produced intracellularly within specialized cells. Melanin pigments, eumelanins and pheomelanins, can be described today as collections of mol. species with different chem. structures and properties, thus encompassing diverse degrees of chem. heterogeneity. This mol. heterogeneity can be ascribed to a no. of factors, including the range of different monomer units; the different mdes of inter-unit coupling; differences in mol. wt.; the redox state; and the extent and mode of aggregationFile in questo prodotto:
