BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In 1891, Emil Fischer determined the structures of glucose and seven other D-aldohexoses using only simple chemical reactions and clever reasoning about stereochemistry and symmetry. He received the Nobel Prize for this work in 1902.

Detailed explanation-2: -Emil Fischer, a German organic chemist, discovered caffeine and other related purines. He also studied the molecular structures of sugars and proteins. For his work he was awarded the 1902 Nobel Prize in Chemistry.

Detailed explanation-3: -Emil Fischer’s discovery of the configuration of glucose.

Detailed explanation-4: -In 1884, Fischer discovered a key reaction in the study of sugars. He went on to determine the structures of glucose, fructose, mannose, and the group of sugars known collectively as hexoses.

Detailed explanation-5: -Fischer esterification or Fischer–Speier esterification is a special type of esterification by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. The reaction was first described by Emil Fischer and Arthur Speier in 1895.
