Our skin color is determined by a pigment called melanin, and while everyone has melanin (both fair and dark-skinned people), it comes in different forms and ratios. The two forms of melanin are calledeumelanin and pheomelanin. Eumelanin comes in primarily brown and black hues, while pheomela...
"Our review paper concludes that melanin, the pigment responsible for skin color, shows a surprising affinity for certaindrug compounds," said Simon Groen, an assistant professor of evolutionary systems biology in the Institute of Integrative Genome Biology at the University of California, Riverside, ...
When a person is unable to produce melanin, he or she may be diagnosed with a condition known as albinism. This is an inherited, congenital condition that comes in different forms as a result of several genetic variations and can affect both men and women, regardless of nationality or ethnic...
Melanoma is cancer of the melanocytes, or cells which produce the pigment melanin. Though they are common in skin, where they are responsible for skin coloration, they can be found throughout the entire body. Answer and Explanation:1
Melanin is produced in a specific cell-type called melanocytes found in skin, eyes and hair follicles. Melanin is alsofound in the brain. The type and amount of melanin and how it is distributed in cells is what creates differences in hair, skin and eye color. ...
Melanocytes are the skin cells responsible for giving skin its color. Although they are found deep in the stratum basale, the deepest layer of the epidermis, they transfer pigment chemicals called melanin to the neighboring keratinocytes.Answer and Explanation: ...
Theepidermisis the thinnest of the skin layers and is also the outermost one. It has the important role of serving as our armor against infections and diseases. It also contains melanin, a pigment that gives our skin its color (we'll talk more about that in another section). ...
Nina Jablonksi from Penn State University talked about the evolution of human skin color and why the gradient of skin color in humans exists. To begin this video she started by talking about melanin, which is the main pigment in human skin. Melanin is produced in the lower layer of skin ...
the amount of melanin made ranges from none to almost the normal amount. This can affect appearance — without melanin, hair and skin are both white. However, a person with slightly reduced melanin may look just like his unaffected parents and siblings [source:Oetting]. Doctors often diagnose ...
Vitiligo is an autoimmune disease that causes the skin to lose its color. Smooth white patches of skin appear as the immune system destroys the skin cells that make melanin. It may also affect hair color and the hair in the inner ear. ...
