and carbon. Starch consists of two types of polysaccharides called amylose and amylopectin1.The properties of starch can depend on the number of alpha 1‚4 glycosidic bonds and the nature of branching. It also is the starting material for ethanol production. Ethanol production is composed of 5 general steps‚ grinding‚ cooking‚ fermentation‚ distillation and benefitability. Alpha amylase is used during the cooking step to hydrolyse starch into fermentable sugars2. Alpha amylase uses amino acids on the

Abstract: Enthalpy of vaporization of ethanol was determined by measuring change in temperature and pressure of ethanol using a Vernier temperature probe. By using the ideal gas equation‚ and plugging the slope value from the graph into the Clausius-Claypernon equation‚ enthalpy of vaporization was determined to be 10kJ/mol. The percent error was determined to be 76.0%. Introduction: The purpose of this lab is to investigate vapor pressures and the partial pressure of gas produced from liquids

variable of alcohol to affect the dependant variable of the amount of DNA extracted. This was done to find out if primary or secondary alcohol would create more DNA precipitate than the other. For this the primary alcohols used were; methanol and ethanol‚ and the secondary alcohol was; isopropyl. Of this the secondary alcohol‚ isopropyl was discovered to be the most effect alcohol to make DNA precipitate‚ as it produced the most amount of DNA. This investigation of extracting DNA is significant due

Why Did Global Food Prices Rise? 1. Farmers in the United States and in Europe benefit from government policies to promote the production of ethanol because they receive government subsidies to produce crops that can be turned into biofuels and it gives the farmers an incentive to plant crops such as corn and soybeans. However‚ this policy harms foreign producers of these foreign crops. Since U.S. and European farmers have subsidies‚ they have lower costs than the foreign farmers and the foreign
