there were trace amounts at the bottom. Overall‚ my conclusion is that only acidic solutions inhibit Amylase’s ability to digest starch. Background The goal of the experiment is to test whether or not Amylase can withstand abnormal changes in pH without denaturing itself. Salivary Amylase is an enzyme that acts upon any polysaccharide that enters the mouth (mainly starch). However‚ it has a few other clinical uses. It is used for the diagnosis of acute pancreatitis‚ an inflammation of the pancreas

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

to gelatin‚ then it will turn. If Benedict solution is added to butter‚ then it will turn. If iodine is added to starch‚ then it will turn. If Benedict color is added to apple juice‚ then it will turn. If any organic substance is tested with distilled water‚ then nothing will happen. Materials: -12 test tubes -Test

precipitate. A non-reducing sugar will be verified by a negative test of Benedict’s solution before hydrolysis by acids‚ followed by a positive test of its hydrolysis into monosaccharide components. The iodine test is done to identify glycogen and starch. The polysaccharides combine with the iodine which will give out a black-blue coloration. There are two tests that are commonly used to test for protein which are the Millon’s and Biuret’s test. A Millon’s test detects the amino acid tyrosine and

follow the activity of amylase because it has a major role in the life of living organisms and is found abundantly in them. Amylase is a catalytic enzyme which hydrolyzes starch into maltose and dextrin at a certain temperature (Biology.kenyon.edu‚ 2015). In plants such as fruits and vegetables carbohydrates are referred to starch which is polysaccharide and is converted into disaccharide and eventually into monosaccharide such as glucose with the help of amylase.

are enzymatic desizing and oxidative desizing. Acid steeping is a risky process and may result in the degradation of cotton cellulose while rot steeping‚ hot caustic soda treatment and hot washing with detergents are less efficient for the removal of the starch sizes. * Enzymatic desizing : Enzymes are solubilizing bio catalysts‚ mainly proteins‚ thermo labile (readily changed or desized by heat) and highly specific in their action.
