The Red and the Black

Simon, John D.; Peles, Dana N. (AMER CHEMICAL SOC, 2010)

Pigmentation, which is primarily determined by the amount, the type, and the distribution of melanin, shows a remarkable diversity in human populations, and in this sense, it is an atypical trait.-E.J. Parra. Melanin is ...
The Ultraviolet Absorption Coefficient of Melanosomes Decreases with Increasing Pheomelanin Content

Peles, Dana N.; Simon, John D. (AMER CHEMICAL SOC, 2010)

Uveal melanosomes from the iridal stroma contain both eumelanin and pheomelanin, the ratio of which varies with iris color. Herein, we report the absorption coefficient at lambda = 244 nm for individual human iridal stroma ...
Ultraviolet Absorption Coefficients of Melanosomes Containing Eumelanin As Related to the Relative Content of DHI and DHICA

Peles, Dana N.; Lin, Erica; Simon, John D. (AMER CHEMICAL SOC, 2010)

Central to understanding the photochemical function(s) of melanosomes is the determination of their absorption properties and an understanding of how the absorption varies with the molecular composition of melanin. Herein, ...
