Melanosomes are organelles found in a wide variety of tissues throughout the animal
kingdom and exhibit a range of different shapes: spheres of up to∼ 1 μm diameters and …

Establishing structure–property relationships in the black insoluble eumelanins, the key
determinants of human pigmentation and skin photoprotective system, is a considerable …

Pheomelanogenesis is a complex pathway that starts with the oxidation of tyrosine (or
DOPA, 3, 4‐dihydroxyphenylalanine) by tyrosinase in the presence of cysteine, which …

The mechanism of action of tyrosinase on monophenols is complex, several processes
overlap in time, such as the hydroxylation of monophenols to o-diphenols, the oxidation of …

Featured Application The recycling of the external peels of pomegranate represents an
important goal for pomegranate juice manufacturers, since their disposal is expensive and …

It is generally considered that eumelanin (EM) is photoprotective while pheomelanin (PM) is
phototoxic. A recent study using a mouse model demonstrated that PM produces reactive …

Mussels-inspired melanin coatings from L-DOPA are getting growing attention by virtue of
their facile synthesis and low-cost production. However, the spontaneous DOPA-melanin …

Melanins are complex, polymeric pigments with interesting properties like UV-light
absorbance ability, metal ion chelation capacity, antimicrobial action, redox behaviors, and …

Since the possibility to biotechnologically produce melanin by Streptomycetes using plant
biomass has been so far poorly investigated, Posidonia oceanica egagropili, a marine waste …

The kinetic action of tyrosinase on l-tyrosine and l-Dopa as substrates in the presence of
