Group Members: Johnny Nguyen‚ Therese Pham‚ Linda Tang Name of Enzyme You are Investigating: Amylase Brief Background: Amylase is a digestive enzyme‚ produced mainly by the salivary glands and the pancreas‚ to break down starch in food into smaller carbohydrate molecules and disaccharides such as maltose. It can be found in humans and some other mammals. Some plants and bacteria may also produce amylase. After being broken down into smaller carbohydrate molecules‚ it can be converted into a monosaccharide

In the experiment‚ the enzyme amylase was involved in saliva. 2. The enzyme act as a catalyst in the experiment and it lowers the activation energy needed and increase the rate of

Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under

To show the action of hydrochloric acid in two carbohydrate solutions. Apparatus & Equipment’s: Boiling tubes Metal test tube racks Beaker Graduated plastic dropper Water bath‚~37°C Water bath‚~95°C Stop watch
Premium Starch Enzyme Amylase
Amylase is found in saliva and breaks starch into maltose and dextrin. This form of amylase is also called "ptyalin" /ˈtaɪəlɪn/[4] It will break large‚ insoluble starch molecules into soluble starches (amylodextrin‚ erythrodextrin‚ and achrodextrin) producing successively smaller starches and ultimately maltose. Ptyalin acts on linear α(1‚4) glycosidic linkages‚ but compound hydrolysis requires an enzyme that acts on branched products. Salivary amylase is inactivated in the stomach by gastric acid

The Effects of Temperature on the Action of Diastase on a Starch Suspension Hypothesis: The practical being carried out is to observe the effects of temperature on starch break down using a synthesized version of salivary amylase‚ this being Diastase. The starch will be placed into the Diastase and water and then placed in baths of water of different l. temperatures. The test tube containing water will have little or no reaction at all. However‚ the test tube containing the Diastase

What conditions are necessary for digestion of lipids‚ carbohydrates‚ protein? Certain conditions are required for digestion. I will find that enzyme is required for digestion of lipids‚ carbohydrates‚ protein. There are many conditions that are necessary for digestion of lipids‚ carbohydrates‚ protein such as pH and enzyme and substrate. The test tube that digestion of lipids occurs in was test tube 1‚3‚4‚ test tube 2 there was no digestion because there was no enzyme. Test tube 1 was the fastest

Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures. Maydelis Perez PI 4593042 Florida International University BSC 1010L‚ section UO9‚ March 6‚ 2013 Abstract Enzymes are very specific protein because they contain one active site on their surface that enable the substrate to bind to the enzyme and form the enzyme substrate complex and then release

of pH on amylase activity This practical allows you to: * discover how pH affects the rate of an enzyme controlled reaction * evaluate the experimental procedure Procedure SAFETY: Follow your teacher’s instructions for handling the solutions. Wear eye protection when handling the iodine solution. Investigation * Place single drops of iodine solution in rows on the tile. * Label a test tube with the pH to be tested. * Use the syringe to place 2 cm3 of amylase into the
