haem part of haemohlobin is a metaloporphyrin, a tetrapyrrole ring with one fe2+ attached to the four nitrogen atoms from four pyrrole rings.
The electrolyte iron is important in the production of hemoglobin.
copper's role in iron metabolism makes it a key factor in hemoglobin synthesis
Iron is essential for hemoglobin formation in the blood. It helps transport oxygen from the lungs to the tissues throughout the body. Iron deficiency can lead to anemia, which can have negative effects on overall health.
Everyone needs iron. But for the formation of hemoglobin and for brain development and function.
iron
Iron plays a critical role in the formation of hemoglobin.
Iron is the mineral responsible for the formation of hemoglobin in red blood cells. It binds to oxygen and helps transport it throughout the body to support various bodily functions. An iron deficiency can lead to anemia and other health complications.
Iron. Vitamin B6 & Copper are also necessary.
Iron is necessary for the blood to function. It can form without iron but to carry oxygen, the hemoglobin molecules in red blood cells require iron.
Iron is bound to the center of hemoglobin, which transports oxygen. Depending on the meaning of element in the question, it could be Iron(most likely) or hemoglobin. ADDED: It is the iron: 4 iron molecules held within the haemoglobin molecule's hydrocarbon lattice. The oxygen binds physically to the Fe without reacting chemically.
hemoglobin
Hemoglobin is a protein and it has an iron ion that can attract an oxygen molecule to it. Both proteins and iron can be found in food.
