text: These chemical properties make melanins beneficial pigments in many ways different from sunlight absorption  as they can act as(a)redox polymers, buffering the level of other intracellular redox biomolecules inside the cell;(b)radical scavengers, for the neutralization of ROS and other reactive oxygenated species;(c)ion chelating agent and possibly exchanger; melanin is able to chelate metal ions through its carboxylated and phenolic hydroxyl groups, in many cases with high affinity and efficiency; thus, it may serve to sequester potentially toxic metal ions, protecting the rest of the cell;(d)polymers with strong capacity to bind a variety of organic molecules, xenobiotics, and aromatic and lipophilic compounds;(e)a protection shield for encapsulating and isolating structures, such as fungal spores, reinforcing cell walls and insect exocuticle;(f)semiconductor materials with high capacitance useful for nanotechnological devices.
