What type of melanin is primarily produced in individuals with light-colored skin?

• A. Eumelanin
• B. Pheomelanin
• C. Melanin derivatives
• D. Carotenoids

Answer: (B)

Individuals with light-colored skin primarily produce pheomelanin, which is a type of melanin that has a lighter color, such as yellow to red hues. Pheomelanin is synthesized in melanin-producing cells known as melanocytes, and its production is more prominent in those with fair skin. This type of melanin contributes to the lighter pigmentation seen in individuals with traits such as blonde or red hair and is less effective in providing UV protection compared to eumelanin, which is darker and provides more efficiency against sun damage.

In contrast, eumelanin is the form of melanin found in darker skin tones and hair colors, incorporating brown to black shades. The other options, such as melanin derivatives and carotenoids, refer to different compounds or pigments that are not the primary focus when discussing the melanin types produced in human skin. Melanin derivatives are products of eumelanin or pheomelanin metabolism, whereas carotenoids are pigments found in certain plants and do not contribute to the skin pigmentation in humans. Thus, pheomelanin is the correct answer as it closely associates with the characteristics of light-colored skin.
