Compound melanin refers to a complex mixture of pigments found in various organisms, primarily animals. Unlike a single, uniformly structured molecule, compound melanin is a heterogeneous aggregate of melanins and associated proteins, lipids, and carbohydrates. This composition results in a range of colors and properties, from black and brown to red and yellow. The exact makeup of compound melanin can vary significantly depending on the species, the specific tissue, and even environmental factors.

The formation of compound melanin involves specialized cells called melanocytes, which produce melanin granules. These granules are then incorporated into other cellular structures, contributing to the coloration of skin, hair, feathers, scales, and eyes. The structural organization of these components within the granule is crucial for the final color and its physical characteristics. For example, the arrangement of melanin within melanosomes, organelles within melanocytes, affects light absorption and scattering, influencing iridescence or opacity.

Beyond coloration, compound melanin plays vital roles in protection against ultraviolet radiation, acting as an antioxidant, and contributing to thermoregulation. Its complex structure allows for a broader spectrum of light absorption and dissipation compared to simpler melanin forms. Research into compound melanin continues to explore its diverse biological functions and potential applications in areas such as biomaterials and photoprotective agents.
