"Melanin protects from toxins by acting as a binding agent, essentially "trapping" harmful substances within its structure, preventing them from reaching deeper tissues and causing damage; this occurs primarily through its ability to adsorb various chemicals, including heavy metals and certain toxins, onto its surface, effectively neutralizing them and allowing for their slow, non-toxic release from the body.
Key points about melanin's protective function against toxins:
Adsorption capacity:
Melanin has a highly porous structure that allows it to readily bind to a wide range of molecules, including toxins, due to its unique chemical properties.
Pigmented tissues:
Melanin is primarily found in pigmented tissues like skin, hair, and eyes, which is why these areas tend to accumulate and "trap" more toxins compared to other parts of the body.
Slow release mechanism:
Once bound to melanin, toxins are slowly released from the body, minimizing their potential for harm.
Antioxidant activity:
Besides its binding ability, melanin also exhibits antioxidant properties, which can help neutralize harmful free radicals generated by toxins.
