  EMIL FISCHER - LoveToKnow Article on EMIL FISCHER   (Site not responding. Last check: 2007-08-08)
Emil Fischer devoted himself entirely to organic chemistry, and his investigations are characterized by an originality of idea and readiness of resource which make him the master of this branch of experimental chemistry.
Fischer attacked the problem presented by ferments and enzymes, and although we as yet know little of this complex subject, to Fischer is due at least one very important discovery, viz, that there exists some relation between the chemical constitution of a sugar and the ferment and enzyme which breaks it down.
FISCHER, ERNST KUNO BERTHOLD (1824-1907), German philosopher, was born at Sandewalde in Silesia, on the 23rd of July 1824.

Fischer reduced the number of possibilities for the structure of (+)-glucose by considering the optical properties of derivatives of glucose that had the same achiral groups at C
From these data Fischer was able to conclude that the enantiomers of arabinose are represented by the structures A and A', and that glucose must be among the structures 3 and 11, or 4 and 12.
Indeed, Fischer was able, through a number of chemical transformations, to switch the "head" and the "tail" of (+)-glucose to form the enantiomer of (-)-gulose, (+)-gulose.

The constitution of caffeine was settled by E. Fischer (Ann., 1882, 215, p.
Fischer confirmed these results and showed further that oxidation with chlorine water gave monomethyl urea and dimethyl alloxan, pointing to the presence of three methyl groups in the molecule.

 Fischer, Emil
Despite major complications because of stereochemical relations, Fischer was able to use these derivatives to determine the molecular structures of fructose, glucose, and many other sugars, and he was able to verify his results by synthesizing those compounds.
In the course of his stereochemical research, Fischer discovered that there are two series of sugars, the D sugars and the L sugars, that are mirror images of each other.
Fischer's researches on the purines, begun in 1894, culminated in his pioneering efforts to determine the structure of proteins.

 Biography of E. Fischer - Peptides International
Hermann Emil Fischer was born on October 9, 1852, at Euskirchen, (Cologne, Germany).
The areas of chemistry that were impacted from Fischer's work include the discovery of phenylhydrazine, his studies of organic dyes (working with his cousin Otto Fischer, in Munich), and characterization and synthesis of caffeine and theobromine.
Fischer also had obtained optically pure forms of amino acids and used them to produce dipeptides (published in 1901 with Fourneau, Gly-Gly), tripeptides, and later polypeptides, his largest synthetic effort resulting in an octadecapeptide.

One direct approach, known as the Fischer esterification reaction, involves the acid-catalyzed condensation of an alcohol and a carboxylic acid, yielding an ester and water.
Emil Fischer (1852-1919) was a German scientist who received his Ph.D. from the University of Strasbourg, studying with Adolf von Baeyer.
Fischer was the first to synthesize phenylhydrazine, which was an important reagent in his work on elucidating the structures of most of the carbohydrates.

At the turn of the century, Emil Fischer suggested that the structure of an enzyme is matched to the substance on which it acts, in much the same way that a lock and key are matched.

A dipeptide is a molecule consisting of two amino acids joined by a single peptide bond.
The German chemist Emil Fischer obtained the first dipeptide, glycylglycine, in 1901 by the partial hydrolysis of the diketopiperazine of glycine.
Dipeptides are produced from polypeptides by the action of the hydrolase enzyme dipeptidyl peptidase.

 Preamble, 2-Carb-0 & 2-Carb-1
Emil Fischer [16] began his fundamental studies on carbohydrates in 1880.
Emil Fischer introduced the classical projection formulae for sugars, with a standard orientation (carbon chain vertical, carbonyl group at the top); since he used models with flexible bonds between the atoms, he could easily 'stretch' his sugar models into a position suitable for projection.
Emil Fischer assumed the cyclic form to be a five-membered ring, which Tollens designated by the symbol <1,4>, while the six-membered ring received the symbol <1,5>.
