WebIntroduction to Hemoglobin: It is an oxygen/CO 2 carrier protein present in the red blood corpuscles of blood. Hemoglobin is a conjugated chromo-protein having heme as its prosthetic group. Heme is the prosthetic group, not only of hemoglobin but also of myoglobin, cytochromes etc. Hemoglobin is formed by the combination of heme with … WebProsthetic groups are non-peptide (non-protein) compounds that mostly attach to proteins and assist them in different ways. They can be inorganic (metals) or organic (carbon-containing) and bind tightly to their target. Prosthetic groups can bind via covalent (electron-sharing) or non-covalent bonds.

These chains or subunits are globin proteins (two α–globins and two β–globins) and each subunit has a prosthetic haem group
WebBoth hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron (Fe) atom. Hemoglobin and myoglobin are heterotetramers. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind one oxygen molecule.
