Porphyrins

Porphyrins are a group of organic compounds characterized by a ring-like structure made up of four smaller rings containing nitrogen atoms. They play a crucial role in biology, forming the core of molecules like heme in hemoglobin, which carries oxygen in our blood. Porphyrins are involved in processes such as oxygen transport and energy production. Their unique structure allows them to bind metals like iron or magnesium, enabling essential functions. Beyond biology, porphyrins are also studied for applications in medicine and materials science, including imaging, cancer treatment, and photodynamic therapy.
