Understanding Melanin: Structure and Functional Properties
Melanin is a complex biopolymer found in various organisms, where it serves critical functions such as UV protection, free-radical scavenging, and bioelectronic activity. Its unique electronic and optical properties make it highly valuable for technological and biomedical applications.
Melanin Fundamentals
Molecular Structure of Melanin
Melanin is formed through the oxidative polymerization of tyrosine via enzymatic pathways. It is a highly heterogenous material, composed primarily of:
Eumelanin (Black/Brown Pigment)
- Composed of 5,6-Dihydroxyindole (DHI) and 5,6-Dihydroxyindole-2-Carboxylic Acid (DHICA).
- Exhibits broad-spectrum UV absorption, making it ideal for photoprotective applications.
- Displays semiconductor-like properties, enabling applications in organic electronics and bioelectronics.
Pheomelanin (Red/Yellow Pigment)
- Contains benzothiazine and benzothiazole derivatives.
- Possesses antioxidant and free-radical scavenging abilities, beneficial for biomedical and skincare formulations.
Our proprietary bioengineering and purification processes yield high-purity melanin with controlled structural and functional properties, enhancing its performance in cosmetics, pharmaceuticals, semiconductors, and clean energy applications.
