What type of melanin is primarily associated with dark-colored skin?

• A. Phenmelanin
• B. Pheomelanin
• C. Eumelanin
• D. Carotene

Answer: (C)

Eumelanin is the type of melanin primarily associated with dark-colored skin. This pigment is responsible for the darker tones and provides protection against the harmful effects of ultraviolet (UV) radiation from the sun. Eumelanin comes in two forms: brown and black, contributing to the overall pigmentation in individuals with darker skin tones.

The production of eumelanin leads to a higher concentration of this pigment in the skin, which not only affects color but also helps in absorbing sunlight and transforming it into heat, offering some degree of photoprotection. This property makes eumelanin advantageous for individuals living in sun-drenched regions, where skin protection is vital for preventing damage from UV exposure.

In contrast, pheomelanin, which is lighter in color and primarily contributes to red and yellow tones in hair and skin, is not predominant in dark-colored skin. Similarly, carotene is a different pigment entirely, responsible for orange-yellow hues, and is not directly related to the melanin present in skin pigmentation.
