Witryna1 lut 2001 · This review will briefly remind all of us of the basic biology of iron and review the known biological aspects of the role of iron in immune system function (Hershko 1996), the biology of iron in neural functioning (Beard et al. 1993) and the role of iron in muscle function and energy metabolism (Beard and Dawson 1996).

WitrynaIron ions are also vital in haemoglobin. Haemoglobin is made up of four polypeptide chains that each contains an Fe2+ ion each, in the centre of the haem groups. These each bind to one molecule of oxygen each, which means that each Fe2+ ion is important in increasing the efficiency of transportation of oxygen. Hemoglobin (haemoglobin in British English) , abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family Channichthyidae) as well as the tissues of some invertebrates.
