MC1R is a critical gene known to be a major determinant of pig coat colour and is known for its role in regulating the change between eumelanin and pheomelanin biosynthesis pathways in mammals [24,25].
Contrastingly, redheads are born with a genetic variant that causes MC1R to chemically function differently on melanocytes, which leads to less eumelanin and more pheomelanin production.
Eumelanin and neuromelanin give a black color to the pigment epithelium of the retina (Figure 5, F), the substantia nigra ("black substance") in the midbrain (Figure 5, G), and the loci coerulea ("blue spots") in the pons.

In the feathers, the researchers spotted the skinny sausages of iridescent melanosomes and chemical signs of the pigment eumelanin.
As glutathione shifts melanin synthesis pathway from eumelanin to pheomelanin, this may increase the risk of sun-induced malignancies, at least theoretically.
Further more, since GSH causes a switch from eumelanin to phaeomelanin, it may increase UV photosensitivity, DNA damage and skin cancers in previously protected populations.
Other enzymes only adjust to differences in synthesis of eumelanin and pheomelanin [10, 27, 28].
Importantly, it is known that the melanogenetic pathway is shifted from eumelanin toward pheomelanin formation when GSH or cysteine is added to melanocytes or melanoma cell lines.
Hair has two types of pigments: eumelanin (dark brown or black pigment) and phaeomelanin (light, reddish-yellow pigment).
The scientists found granules in the fossil that, when compared to modern fish eyes, are made of eumelanin a pigment that absorbs light and helps animals see, Press Tv reported.
he melanocytes, which produce the melanin, can either produce a red melanin -- pheomelanin -- or dark brown -- eumelanin.
It's the combination of yellow, red and blue pigmentation called pheomelanin and black to brown pigmentation called eumelanin that gives mammals and birds their skin color.
