Carbohydrates <b>Introduction:</b> Carbohydrates are molecules that contain Carbon, Hydrogen, and Oxygen. The most basic sugar- carbohydrate is the monosaccharide. Carbohydrate molecules are categorized by the number of carbons present in the molecule. Glucose, the most common monosaccharide has six carbons per molecule, which is called a hexose. Carbohydrates also have a 2:1 hydrogen to oxygen ratio. This aids in the condensation and hydrolysis reactions. A condensation reaction occurs when two monosaccharides join by the …showed first 75 words of 1342 total…

Once this reaction took place, the Bennedict’s reagent reacted with the mono or disaccharides with a color change of green. The experiments using biuret reagent proved that starch in an acidic environment does not change its molecular structure into peptides. <b>Error:</b> All experiments where subject to the same types of errors. These errors could have been any variation of experimental procedures, chemicals, or data.
