Heme is a key component of hemoglobin, the protein in red blood cells that carries oxygen throughout the body. Research in the area of heme focuses on understanding its role in various biological processes, such as oxygen transport, cell metabolism, and enzymatic reactions. This research also explores the implications of heme dysregulation in diseases such as anemia, porphyrias, and certain types of cancer. Additionally, heme research investigates potential therapeutic interventions targeting heme metabolism for the treatment of these conditions.
