There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. Eumelanin is produced through a multistage chemical...

melanin: eumelanin and pheomelanin. Generally, the more melanin present, the darker the hair. Its tone depends on the ratio of black or brown eumelanin to yellow...

the color of the eumelanin pigment produced, making it either black or brown. TYRP1 is an enzyme involved in the synthesis of eumelanin. Each of the known...

interplay among genes that direct production and expression of two pigments, eumelanin (brown or black pigment) and pheomelanin (yellow to red pigment), in the...

tyrosinase, producing dopaquinone. Dopaquinone may become eumelanin, or phaeomelanin. Eumelanin, meaning true black, is a dense compound that absorbs most...

to dark hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin. Brown hair is common...

involved in the metabolic pathway for eumelanin pigment production. Its dominant form, B, will produce black eumelanin. It has two recessive variants, b (chocolate)...

C8H7NO2. It is an intermediate in the production of the biological pigment eumelanin. 5,6-Dihydroxyindole is biosynthesized from L-dopachrome in a reaction...

dark skin pigmentation have skin naturally rich in melanin (especially eumelanin), and have more melanosomes which provide superior protection against...

markings above the eyes. Eumelanin and phaeomelanin pigmentation occurs on the same dog; "the back is black from eumelanin pigment being made and the...
