| There are two different melanins found in human hair, eumelanin and pheomelanin. |
|
| Plumage color of homozygous birds varies from slaty blue to beige depending on the relative abundance of eumelanin and pheomelanin in the feathers. |
|
| Cats as you know have many different colors, but there are only two different types of pigments: eumelanin, black, and phaeomelanin, red. |
|
| There are two types of melanin: pheomelanin which is yellow coloured, and eumelanin which is black. |
|
| In the absence of cysteine, indole 5-6 quinone is formed and it is eumelanin that will be synthesised. |
|
| The new work identified the pigment, eumelanin, based on trace amounts of metals in the fossils. |
|
| Lasers with wavelengths of 600-1100 nm penetrate deeply and are absorbed by eumelanin in the hair shaft and follicle, which is thought to be the target chromophore. |
|
| Light energy of a particular wave length applied using a laser will specifically destroy the pigment found in the bulb of the hairs, the eumelanin. |
|
| A number of different pigments are produced in the different vertebrate groups, but in mammals only brown eumelanin and yellow or red phaeomelanin are important. |
|
| Researchers from Carnegie Mellon University and the University of Oregon have designed a battery with a fully biodegrable electrode made from a molecule called eumelanin, which is found in skin, hair and eye pigments. |
|
| The most common form of biological melanin is eumelanin, a brown-black polymer of dihydroxyindole carboxylic acids. |
|
| Melanocytes produce two forms of melanin, black-brown eumelanin and red-yellow pheomelanin. |
|
| The researchers did a similar analysis of feathers from present-day birds, and on closer examination, they found that the pattern of copper matched that of eumelanin. |
|
| Quantitative fluorescence excitation spectra of synthetic 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. |
|
| That tiny difference prevents the tiger from making the reddish and yellow pheomelanin pigments, but does not affect the production of the black pigment eumelanin. |
