Red blood cells (RBCs) contain a form of globular protein called haemoglobin (Hb), which carries oxygen throughout our bodies through the blood. It is a tetrameric protein, and each component of it has a heme prosthetic group attached.
Red blood cells (RBCs) contain a form of globular protein called haemoglobin (Hb), which carries oxygen throughout our bodies through the blood. The heme prosthetic group is joined to each member of this tetrameric protein. It functions as a respiratory pigment and aids in the movement of oxyhaemoglobin, which carries oxygen from the lungs to various body regions. Carbon dioxide is also carried back through haemoglobin as carbaminohaemoglobin in small amounts.
"Hb" is the commonly used shorthand for haemoglobin.
Myoglobin in muscles, haemocyanin in arthropods and mollusks, leghaemoglobin in legumes, etc. are examples of other oxygen-binding proteins. Human haemoglobin A is encoded by the HBA1, HBA2, and HBB genes. Different species have different variations in the order of amino acids in Hb polypeptide chains.
