Structure of hemoglobin and myoglobin
WebHaemoglobin (Hb) is widely known as the iron-containing protein in blood that is essential for O2transport in mammals. Less widely recognised is that erythrocyte Hb belongs to a large family of Hb proteins with members distributed across all three domains of life-bacteria, archaea and eukaryotes. WebIt serves as an oxygen reservoir, picking up O2 from the hemoglobin and delivering it to the cells as O2 is used up in metabolism. Sperm whale myoglobin consists of 153 amino …
