Biological pigments are chemical compounds responsible for imparting color to living organisms. These compounds vary widely in their chemical structure, encompassing organic molecules such as chlorophylls, carotenoids, and various melanins. Beyond their role in visual coloration, pigments are often integral to core biochemical processes. For example, in plant life, pigments are critical components of photosynthetic machinery, harvesting light energy. In animal tissues, they can function in oxidative stress management, UV protection, or as structural signaling molecules. The synthesis and function of these pigments are highly regulated metabolic pathways, demonstrating how molecular structure directly translates into essential physiological roles within biological systems.
