This report discusses an experiment to asses the chemical break toss off of starch into maltose (sugar) in the presence of the enzyme amylase, a digestive process deep down the body. Nutrients fundament be absorbed only when broken down to their monomers (small molecules that breakdown further to other molecules). Enzymes are large protein molecules produced by body cells. They are biological catalysts, meaning they increase the subprogram of a chemical reaction without themselves becoming part of the product. digestive enzymes are hydrolytic enzymes. Their substances, or the molecules on which they act are natural food molecules which they breakdown by adding water to the molecular bonds, therefore cleaving the bonds between the subunits or monomers. Digestive enzymes can function after-school(prenominal) the body cells; their activity can be studied by test tubes (Marieb and Mitchell 2010). This experiment attempts to re-create the breakdown process that is usually done via digestion with Iodine as a vital component. It can be expected that once amylase reacts with the starch, maltose leave thus be broken down and less starch will be visible and more sugar will be apparent thus causing the solution mixed with tincture of iodine to become lighter and lighter.

Method/Procedure
1. Identification of Starch
To be able to identify the presence of starch, it was necessary to make a ensample test by using IKI in easys on the spot plate. Three wells on the spot plate were filled with one drop of IKI each. In the first well two drops of water was mixed with the IKI to show what a forbid control looked like. Then two drops of starch was added to the second well, which exhibit a...If you want to get a full essay, order it on our website: Ordercustompaper.com
