The "Barts" variant is a result of gene deletion in infants, and usually results in death from hydrops fetalis.

The "Barts" variant is a result of gene deletion in infants, and usually results in death from hydrops fetalis. When it breaks down, its parts are salvaged by transferrins and reprocessed to form bilirubin. Like chlorophyll, this protein is a chelate. The A type is normal and the F type is found in developing fetuses, while another type found almost exclusively in groups of African descent contains a mutation in the beta chain. That type, called S, causes sickle-cell anemia. Found in erythrocytes and synthesized in the bone marrow, it consists of four heme subunits, each bound to one atom of iron. For 10 points, name this oxygen-carrying protein that gives blood its red color.
