Bird Coloration: Mechanisms and measurements
There are two main forms of melanin — eumelanin and phaeomelanin — that
differ in granule size and shape, chemical composition (e.g., phaeomelanin
contains sulfur), and color (eumelanin tends to be black/gray whereas
phaeomelanin is ...
Geoffrey Edward Hill, Kevin J. McGraw, 2006
In hair colors, particularly ash-colored hues, the retention of phaeomelanin is
sharply reduced. Judging by the data of the Russian anthropological expedition,
dark brown hair turns out to be a predominant trait in the Russian population, ...

Genetics and Evolution of the Domestic Fowl
There are two principal types of melanocytes responsible for the formation of
feather pigment: those producing the black melanin, eumelanin, and those

Biological Perspectives on Human Pigmentation
There are two main types of melanin important in human biology — eumelanin
and phaeomelanin.1 Eumelanin is the black-brown compound that has been
discussed thus far: it is found in the skin, hair and all the other melanocyte-
bearing ...
The metabolism of phaeomelanin arises by a deviation from the eumelanin
pathway; the principal reaction involves the addition of cysteine to dopaquinone
to produce 5-S-cysteinyldopa (Fig. 1) and, to a lesser extent, the 2-isomer (Prota,
...

National Geographic Bird Coloration
PHAEOMELANIN Phaeomelanin creates a range of color displays in feathers. At
one extreme, it produces relatively bright gold, auburn, or rust as on the hacklcs
and back feathers of the wild-type domestic rooster (Red Iunglefowl) and on the ...

Atlas of Human Hair: Microscopic Characteristics
The inability to resolve individual pigment granules may be due to the small size
of the granules (e.g., phaeomelanin pigment) or the obscured effect caused by
heavy pigmentation when looking at the hair in a longitudinal mount (e.g.,
opaque ...

The Structure and Function of Skin 3E
The brownish-yellow pigment commonly found in blonde and red hair is
phaeomelanin. Eumelanin and phaeomelanin have common pathways; at some
stage in the formation of eumelanin, some intermediate products react with
cysteine to ...
