Melanin polymerization occurs through auto-polymerization of aromatic rings to form the big polymer. How do this occurs without any enzyme help? Is this polymerization contribute to its solubility? Is the aromatic ring incorporation occurs randomly in melanin structure?
Once tyrosinase catalyzes the oxidation of o-diphenols to o-quinones, the polymerization can occur and occurs spontaneously. Nevertheless, there are some enzymes involved, as the same tyrosinase or the TRPs (tyrosinase related proteins 1 and 2). See a review for details.
Hi Solano
Spontaneous means How ? that is my question.Is there any pattern for this.Is melanin polymerization occurs at different environment differ in their structure ?
I think this paper is good for u;
Synthetic melanin.

Hi Fatemeh
The suggested paper help me a lot in understanding melanin chemistry. But my doubt still remains.Thanks a lot for helping me to know more.It will surely add to my research
Seem that this reaction is not spontaneous, naturally is necessary Cu++ ions as catalyzer (also as cofactor), or in the most of synthetic cases heat, oxidants agents and ionizing radiations.
