Hemoglobin (haemoglobin, [a] Hb or Hgb) is a protein containing iron that facilitates the transportation of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, [ 3 ] with the sole exception of the fish family Channichthyidae . [ 4 ]

The beta chain will pair with the alpha chain. It is the combining of two alpha and non-alpha chains which create a hemoglobin molecule. Two alpha and two gamma chains form fetal hemoglobin or hemoglobin F (HbF). After the first five to six months after birth, the combining of two alpha chains and two beta chains form adult hemoglobin (HbA).
Lowercase letters may then be freely used for cytochromes and enzymes, as well as to describe individual protein-bound heme groups (for example, cytochrome bc, and aa3 complexes, cytochrome b 5, heme c 1 of the bc 1 complex, heme a 3 of the aa 3 complex, etc)." In other words, the chemical compound would be designated with a capital letter, but ...
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...

Of this, about 2.5 g is contained in the hemoglobin needed to carry oxygen through the blood (around 0.5 mg of iron per mL of blood), [25] and most of the rest (approximately 2 grams in adult men, and somewhat less in women of childbearing age) is contained in ferritin complexes that are present in all cells, but most common in bone marrow ...
The globins are a superfamily of heme-containing globular proteins, involved in binding and/or transporting oxygen. These proteins all incorporate the globin fold, a series of eight alpha helical segments. Two prominent members include myoglobin and hemoglobin. Both of these proteins reversibly bind oxygen via a heme prosthetic group.
