10 ENGLISH BOOKS RELATING TO «EUMELANIN»
Discover the use of
eumelanin in the following bibliographical selection. Books relating to
eumelanin and brief extracts from same to provide context of its use in English literature.

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 ...

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].
