Découvrez l'usage de
eumelanin dans la sélection bibliographique suivante. Des livres en rapport avec
eumelanin et de courts extraits de ceux-ci pour replacer dans son contexte son utilisation littéraire.
The synthesis of eumelanin requires tyrosinase, an enzyme located in
melanosomes. Tyrosinase catalyzes the conversion of tyrosine to dopa, which is
further oxidized to dopaquinone. Through a series of enzymatic and
nonenzymatic ...

ECS transactions [Electronic journal].
In the 90's, progress in scanning probe and x-ray techniques brought new insight
in the eumelanin structure. Several works suggested a different structure for
eumelanin, the stacked oligomer model (16-20). Atomic Force Microscopy and X-
ray ...

Encyclopedia of Genetics
Mice with this or other loss-of-function alleles of Tyrpl produce brown rather than
black eumelanin, and partial loss of function results in dark brown eumelanin.
The Tyrpl gene in rats localizes to the brown mutation, but the sequence change

The photochemical degradation by VIS light of eumelanin, the predominant
pigment of black and light brown hair, is relatively small and can be shown
quantitatively (gravimetry) and qualitatively (color measurements, IR
spectroscopy) [29].
