What is heme can?

Heme is an iron-containing molecule that is essential for life. It is found in many different proteins throughout the body, including hemoglobin, myoglobin, and cytochromes. Heme plays a critical role in oxygen transport and storage in red blood cells, as well as in many other biological processes such as the production of energy in the mitochondria. Heme is synthesized in the body through a multi-step process that involves several enzymes and requires the presence of iron. It can also be obtained through the diet from foods such as red meat, poultry, fish, and plant-based sources like lentils and spinach. Heme can also have potential negative health effects, as high levels of heme iron intake have been associated with an increased risk of some diseases, such as cancer and cardiovascular disease.
