“We may regard the cell quite apart from its familiar morphological aspects, and contemplate its constitution from the purely chemical standpoint. We are obliged to adopt the view, that the protoplasm is equipped with certain atomic groups, whose function especially consists in fixing to themselves food-stuffs, of importance to the cell-life. Adopting the nomenclature of organic chemistry, these groups may be designated side-chains. We may assume that the protoplasm consists of a special executive centre (Leistungs-centrum) in connection with which are nutritive side-chains... The relationship of the corresponding groups, i.e., those of the food-stuff, and those of the cell, must be specific. They must be adapted to one another, as, e.g., male and female screw (Pasteur), or as lock and key (E. Fischer).” ScienceChemistryFischerCellNobel LaureatePasteurOrganic ChemistryAtomic TheoryLouis PasteurEmil FischerHermann Emil Fischer Author:Paul Ehrlich
“First I would like to wash Bunsen, and then I would like to kiss him because he is such a charming man. (Remark by the wife of Emil Fischer, upon meeting Bunsen for the first time, perhaps noticing a lasting chemical odour from his work.)” BunsenRobert BunsenEmil FischerRobert Wilhelm Eberhard Bunsen Author:Agnes Fischer
