Abstract This experiment was carried out to monitor the ability of the Barley Amylase Enzyme to effectively break down starch in solutions that are increasing in neutral pH. To do this the experiment was carried out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After

Glucose Change in color Color changed to a dark red 2. Starch Change in color Color changed to a dark red 3. Onion Juice Change in color Color changed to a dark red 4. Distilled Water No change No change in color The test tube with the Glucose‚ Starch‚ and onion juice were the positive controls. The

by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for the Dye test was to test for lipids. When mixed with water and the tested substance‚ a positive result will occur in it being separated from the water. The

IODINE TEST FOR STARCH The Iodine test is used to test for the presence of starch. Iodine solution — iodine dissolved in an aqueous solution of potassium iodide — reacts with the starch producing a purple black color. The colour can be detected visually with concentrations of iodine as low as 0.00002M at 20°C. However the intensity of the colour decreases with increasing temperature and with the presence of water-miscible‚ organic solvents such as ethanol. Also the test cannot be done at very low

clean” and “Magic power”. Principal: Amalyse can catalyse the breakdown of starch into maltose. In this practical‚ solutions of the 2 washing powders will be filled into 2 identical wells on the starch agar plate separately. Starch will be broken down by the amylase disused to the star-agar. A clean zone will be formed around the wells when iodine solution is added and flushed. The higher the amylase activity‚ the more the starch will be broken down. Hence‚ a larger and clearer zone will be observed

CHAPTER ONE 1.0 INTRODUCTION Starch is one of the most abundant substances in nature‚ a renewable and almost unlimited resource. Starch is produced from grain or root crops. It is mainly used as food‚ but is also readily converted chemically‚ physically and biologically into many useful products to date; starch is used to produce such diverse products as food‚ paper‚ textiles‚ adhesives‚ beverages; confectioning‚ pharmaceuticals‚ and building materials. Cassava starch has many remarkable characteristics

rate of amylase in starch? In this experiment diluted solutions of amylase were created and then tested using a starch solution‚ I2KI for reaction times. The answer to the question was proved to be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva of most animals and in humans. Amylase hydrolyzes starch‚ a plant’s reservation of carbohydrates. Amylase causes a chemical reaction in the polysaccharide starch that breaks down

consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which contained liquid solution of iodine. Each environment contained two different test tubes‚ one test tube was starch and the other was amylase. A droplet was placed in ten to thirty second intervals to see the different states of starch break up. When starch is present with iodine‚ the solution is a dark
