Function of heme
WebIts main function is scavenging the heme released or lost by the turnover of heme proteins such as hemoglobin and thus protects the body from the oxidative damage that free heme can cause. In addition, hemopexin releases its bound ligand for internalisation upon interacting with CD91. [16] Hemopexin preserves the body's iron. [17] WebHeme is a key molecule for most living cells; it is the cofactor of several essential reactions involved in energy metabolism, detoxification of noxious compounds, and sensing …

WebHeme oxygenase-1 (HO-1) plays a vital role in the catabolism of heme and yields equimolar amounts of biliverdin, carbon monoxide, and free iron. We report that macrophages engulfing either the low amount of heme-containing apoptotic thymocytes or the high amount of heme-containing eryptotic red blood cells (eRBCs) strongly upregulate HO-1.
