Aug. 5, 1957, Munich), German chemist, winner of the 1927 Nobel Prize for Chemistry for his research on the bile acids. Working at the University of Munich, he made important contributions to structural organic chemistry with his findings (1911) that different forms of nitrogen in organic compounds can be detected and distinguished from one another. The following year he began his research on bile acids, which are produced by the liver. He found that the three acids then isolated were of similar structure and were also structurally related to cholesterol. His later work led him to believe that oxidation in living tissues is a matter of removing hydrogen atoms (dehydrogenation) and not of adding oxygen. This theory proved of great importance to physiology, biochemistry, and medicine. Related Propaedia Topics: Associated glands and structures: pancreas, liver, gallbladder, and bile ducts

During the selection process in 1927, the Nobel Committee for Chemistry decided that none of the year's nominations met the criteria as outlined in the will of Alfred Nobel. According to the Nobel Foundation's statutes, the Nobel Prize can in such a case be reserved until the following year, and this statute was then applied. Heinrich Wieland therefore received his Nobel Prize for 1927 one year later, in 1928. TO CITE THIS PAGE: MLA style: "The Nobel Prize in Chemistry 1927".

Wieland, Heinrich Otto Wieland est né à Pforzheim (Grand-Duché de Bade) le 4 juin 1877. Après avoir fait ses études supérieures aux Universités de Munich et de Berlin, puis à l'Ecole Polytechnique de Stuttgart, docteur en 1901, il est nommé lecteur à l'Université de Munich en 1904, puis professeur cinq ans plus tard. En 1913, il prend la direction du département de chimie organique, puis travaille de 1917 à 1918 au Kaiser Wilhelm Institut de chimie, à Berlin-Dahlem. Ensuite il occupe successivement un poste de professeur à Freiburg, puis à Berlin où, en 1925, il succède à Willstatter. Dans ses premiers travaux effectués à Munich, il s'intéresse aux mécanismes d'oxydation chez les êtres vivants : l'oxygène transporté par le sang réagit avec les substances hydrocarbonées pour donner du co,et de la vapeur d'eau. Wieland s'astreint à démontrer que les phénomènes d'oxydation sont très souvent dus à des processus de déshydrogénation, tout comme dans la rouille de fer; l'oxydation des composés intermédiaires qui apparaîï dans l'organisme est due à un transport d'hydrogène du métabolite vers un accepteur d'hydrogène. Mais durant de longues années il étudie surtout des substances naturelles telles que les alcaloïdes, les acides biliaires et les composés violemment toxiques. Ainsi, pendant que son ami Windaus travaille sur les dérivés de la digitaline (cardiotonique), Wieland tente d'élucider la structure des poisons d'origine animale agissant sur le coeur, comme par exemple la toxine que fabriquent certains crapauds. En collaboration avec C. Sch?pf, il cherche par ailleurs à déterminer la structure des pigments des ailes de papillons, et trouve des substances analogues dans les écailles de poissons. Ce sont ces travaux qui le rendent célèbre, et lui valent le prix Nobel de 1927.

Wieland effectue ses études de chimie à Munich, Berlin et Stuttgart. Il retourne à Munich où il obtient son doctorat en 1901. C'est à Munich que va s'effectuer l'essentiel de sa carrière.  Ses premiers travaux concernent les réactions des oxydes d'azote, le mécanisme de la nitration des hydrocarbures aromatiques et la chimie des hydrazines qui l'amène à obtenir les premiers radicaux libres azotés. En 1917-1918, il est détaché à Berlin auprès de Fritz Haber pour participer à l'effort de guerre chimique allemand. En 1925, il succède à Richard Willstätter à la direction du fameux laboratoire Baeyer à Munich, poste qu'il va assumer jusqu'à sa retraite en 1950.  Il s'intéresse très tôt aux réactions d'oxydation biologique et montre qu’elles sont très souvent des déshydrogénations.
