The Nobel Prize in Chemistry 1902 was awarded to Emil Fischer "In recognition of theextraordinary services he has rendered by his work on sugar and purine syntheses." Fischerexamined the properties of enzymes, the substances responsible for the fermentation of sugars.He laid the foundations for enzyme chemistry and provided a new perspective concerning theaction of enzymes. In 1894 he tested the action of yeasts on various sugars and noted thespecificity of enzymes: maltase, for example, hydrolyzed a-methyl glucoside but not B-methylglucoside, while emulsion hydrolyzed B-methyl glucoside but not a-methyl glucoside. Forsugars of identical composition but different stereometric configuration, an enzyme was activeonly with a particular configuration. He concluded that enzymes were asymmetric agentscapable of attacking molecules of only specific geometric configurations. The action ofenzymes in hydrolyzing glucosides led him to use the analogy of a lock-and-key structuralrelationship between the enzyme and the sugar (1894). Molecular asymmetry gained newsignificance: the chemical transformations in the organism depended on asymmetry. (DSB Vol.5, p. 4). Please inquire ABOUT INTERNATIONAL SHIPPING
