The Science of Melanin
Melanin is a complex polymer derived from the amino acid tyrosine. It is produced by specialized cells called melanocytes, primarily located in the skin, hair follicles, and the retina of the eyes. There are three main types of melanin: eumelanin (which can be brown or black), pheomelanin (which is yellow or red), and neuromelanin (found in the brain).
Functions of Melanin
Melanin serves several crucial functions in the human body:
- Protection from UV Radiation: Melanin absorbs harmful ultraviolet (UV) rays from the sun, reducing the risk of skin damage and skin cancer.
- Antioxidant Properties: It acts as an antioxidant, helping to neutralize free radicals that can cause cellular damage.
- Thermoregulation: Melanin helps in regulating body temperature by absorbing heat.
- Vision Protection: In the eyes, melanin protects against harmful light and is vital for proper vision.
The Cultural Significance of Melanin
Throughout history, melanin has been more than just a biological pigment; it has also been a symbol of cultural identity and pride. The perception of skin color has often been intertwined with social status, beauty standards, and even systemic discrimination.
