Web1 aug. 2003 · The heme group in myoglobin is held in place by a single covalent bond from the ‘proximal’ histidine to one of the six heme iron coordination sites. Four other coordination sites are bound to porphyrin pyrrole nitrogens and the sixth site on the ‘distal’ side of the heme is left open for ligand binding. WebHeme, whether leghemoglobin or from meat, is the iron-containing molecule in blood. It’s what put the heme in hemoglobin that we can measure in everyone’s blood. More importantly, straight from Impossible Burger themselves, it’s “something we’ve been eating and craving since the dawn of humanity” and is “essential for life”.
