chem Experiment #2 Chem 272 INTRODUCTION AND BACKGROUND In the biosynthesis of grain alcohol, sucrose (C12H22O11) is hydrolyzed to fructose (C6H12O6) and glucose (C6H12O6) by barm, which contains invertase, an enzyme. The monosaccharides are then catalyzed by zymase. Zymase is a collection of enzymes that are found in yeast and catalyze the individual steps in converting glucose and fructose to ethanol and carbon dioxide. ? Pasteurs salt solution is added to increase yeast increase and also to help the fermentation. In the reaction, the ethanol formed is utilize to kill the yeast cells and hinder the fermentation process.
The ethanol that is produced dissolve never reach 100% pure ethanol. A intermixture of 95% ethanol and 5% water is the highest concentration that chiffonier be obtained by the fractional distillation process. In baffle to produce 100% ethanol solution, the ethanol must be dehydrated after it is distilled. Ethanol, or dehydrated alcohol, by comment is not less th...If you want to get a serious essay, order it on our website:
