Two types of melanin are found in the skin and hair, the brown/black melanin, eumelanin, and the red melanin, pheomelanin [26]. The formation of eumelanin begins with either hydroxylation of intracellular L-phenylalanine or from extracellular tyrosine transported into the cell (Fig. 8.1). L-...

Objective to compare the levels of eumelanin and pheomelanin in nomal and abnormal skin between Chinese and Caucasion. Methods The study was performed with HPLC to analyse the content of eumelanin and pheomelanin in Chinese subjects with and Caucasion subjects with naevocytic naevu, dysplastic mela...
Pheomelanin and eumelanin share the same pathway only during their initial stages of development, which can be a key to unravel the functional importance of pigment allocation and thus of plumage coloration. Using the barn swallow, Hirundo rustica, a migratory species, we found that plasma ...

Eumelanin and pheomelanin were found in all epidermal samples and their relative proportions correlated well with those found in samples of hair taken from the same subjects. The lowest concentrations of eumelanin were found in subjects of skin type I, with higher levels in skin types II and ...
