What are the different types of melanin and how do they vary in terms of their functions and distribution in the human body?
There are two main types of melanin in the human body: eumelanin and pheomelanin. Eumelanin is responsible for brown and black pigmentation, while pheomelanin is responsible for red and yellow pigmentation. Eumelanin provides protection against UV radiation and is found in higher concentrations in the skin, hair, and eyes. Pheomelanin does not provide as much protection against UV radiation and is more commonly found in red hair and freckles.

What are the different types of melanin found in the human body and how do they vary in terms of function and distribution?
There are three main types of melanin found in the human body: eumelanin, pheomelanin, and neuromelanin. Eumelanin is responsible for brown and black pigmentation, while pheomelanin produces red and yellow pigments. Neuromelanin is found in the brain and plays a role in protecting neurons. These types of melanin vary in function and distribution, with eumelanin and pheomelanin primarily found in the skin and hair, while neuromelanin is specific to the brain.
