        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "Heme (American English) or haem (British English) is a cofactor consisting of an Fe2+ (ferrous) ion contained in the centre of a large heterocyclic organic ring called a porphyrin, made up of four pyrrolic groups joined together by methine bridges. Not all porphyrins contain iron, but a substantial fraction of porphyrin-containing metalloproteins have heme as their prosthetic group; these are known as hemoproteins." ] ,
