Question:

What is the primary role of melanin in the body, and where is it primarily found?

Answer:

Melanin is a natural pigment found primarily in various tissues of the body, including the skin, hair, and eyes. Its primary role is to protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun by absorbing and dissipating UV rays. Melanin production is regulated by genetic and environmental factors and is responsible for the variations in skin color among individuals.
