It is found in a number of plants, where its function is unknown. Nitric oxide is distributed throughout the body by this substance and production of it requires iron, vitamin B(12), and folic acid in the diet. Intrinsic factor, produced in the stomach, is necessary for the uptake of vitamin B(12). A lack of intrinsic factor results in pernicious anemia. In lungs, it releases carbon dioxide and takes up oxygen. This protein consists of two parts: a helical chain, and a ring complex made of iron and a porphyrin compound, and is produced in the bone marrow. FTP identify this red-pigmented protein in the red blood cells of all vertebrates and some invertebrates.
