Heme prosthetic groups
WebHeme is an essential prosthetic group for most life on Earth. It functions in numerous cellular redox reactions, including in antioxidant defenses and at several stages of the electron transport chain in prokaryotes and eukaryotic mitochondria. Heme also functions as a sensor and transport molecule for gases such as oxygen. WebHeme is the O 2 – binding molecule common to Mb and Hb protophorphyrin IX is the backbone of heme when iron is complexed with protophorphyrin IX it is called Heme. So heme is the prosthetic group in Hemoglobin, Myoglobin and Cytochrome b, c, and c 1. The Fe – porphyrin prosthetic group is, with the exception of two propionate groups ...
