heme

Heme is a small, yet essential molecule found in our blood. It contains an iron atom at its center, which allows it to carry oxygen from our lungs to the rest of the body. Heme is a component of hemoglobin, the protein responsible for oxygen transport in red blood cells. It also plays a role in other functions, like helping enzymes break down substances and produce energy. Without heme, our bodies wouldn't be able to efficiently deliver oxygen or carry out vital biochemical processes, making it crucial for maintaining health and life.
