Similarities : •Chlorophyll: center atom is magnesium (Mg) • Hemoglobin: center atom is iron (Fe) • Melanin: while not a porphyrin, it has a conjugated aromatic ring network that also allows electron resonance and light absorption. Metal-centered complexes • Chlorophyll: Mg²⁺ is the active metal. • Hemoglobin: Fe²⁺ binds and transports oxygen. • Melanin: often chelates (binds) metals such as Fe, Cu, and Zn — enhancing electron transfer, redox, and photoprotective properties. All derived from ami
