Hans Fischer

born: July 27, 1881, Höchst, Germany

died: March 31, 1945, Munich, Germany

German biochemist who used to be awarded the Nobel Prize for Chemistry in 1930 for analysis into the structure of hemin, the red bloodpigment, and chlorophyll, the green pigment in vegetation.Hemin is a crystalline made from hemoglobin. Through splitting in 1/2 the molecule of bilirubin, a bile pigment associated to hemin, Fischer bought a brand new acid in which a part of the hemin molecule used to be still intact. Fischer recognized its construction and located it to be associated to pyrrole. This made conceivable the artificial synthesis of hemin from simpler organic compounds whose construction was known. Fischer additionally confirmed that there is a close relationship between hemin and chlorophyll, and by the point of his death he had nearly accomplished the synthesis of chlorophyll. He also studied the yellow pigment carotene, a precursor of vitamin A, and the porphyrins, which are iron-free derivatives of hemin extensively distributed in nature and secreted through humans in certain illnesses.
