Pigment Cell & Melanoma Research, 2022 Human skin contains two distinct components: brown to black, insoluble eumelanin and light colored, alkaline‐soluble pheomelanin. Eumelanin consists of 5,6‐dihydroxyindole (DHI) and 5,6‐dihydroxyindole‐2‐carboxylic acid (DHICA) moieties, while ...

International Journal of Molecular Sciences, 2022 The overproduction of eumelanin leads to a panel of unaesthetic hyper-pigmented skin diseases, including melasma and age spots. The treatment of these diseases often requires the use of tyrosinase inhibitors, which act as skin whitening agents by ...

The photoprotection mechanism in the black–brown pigment eumelanin
Proceedings of the National Academy of Sciences of the United States of America, 2022 Significance The black–brown eumelanin pigment plays a major role in humans’ photoprotection against high-energy UV photons by dissipating radiation into heat before harmful radical reactions can damage tissue.

Ultrafast Radical Photogeneration Pathways in Eumelanin †
Photochemistry and Photobiology, 2022 Eumelanin is a ubiquitous biological pigment that rapidly and efficiently deactivates excited states created by UV or visible radiation. Paradoxically, photoirradiation of eumelanin also generates radicals and harmful reactive oxygen species, but the ...

Oxidative physiology is weakly associated with pigmentation in birds
Ecology and Evolution, 2022 The mechanistic link between avian oxidative physiology and plumage coloration has attracted considerable attention in past decades. Hence, multiple proximal hypotheses were proposed to explain how oxidative state might covary with the production of ...
