Heme

Heme, or haem (pronounced /hi:m/ HEEM), is a precursor to hemoglobin, which is necessary to bind oxygen in the circulatory system. Heme is biosynthesized in both the bone marrow and the liver.

Function

Hemes can do many things, such as catalyse reactions or move chemicals. Hemes are usually bound to proteins, which makes what are called hemoproteins.

Examples of hemoproteins include hemoglobin, myoglobin, leghemoglobin, and cytochrome.
