Starch is a type of Carbohydrate that’s made from thousands of glucose units. Simple sugars are the basic units that make up starch. Carbohydrates provide us with energy so that we can carry out our daily routines. Our body then digests it into glucose so we can have energy to do that. Saliva is a form of chemical digestion that is in the mouth. Amylase is an enzyme that catalysts the breakdown of starch into sugars. Amylase is present in human saliva‚ where it begins the chemical process of digestion

Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently
Premium Digestion Enzyme Starch
2013 Title: Starch Digestion by Pancreatic Amylase Statement of the Problem: What happens to enzymes when they are boiled? If digestion doesn’t occur‚ which will be present starch or maltose? If digestion does occur‚ which will be present starch or maltose? Hypothesis: I predict that when enzymes are boiled‚ they will become larger. If digestion does not occur starch will be present‚ and if it does occur maltose will be present. Materials: Test Tube Boiling Water Starch Suspension

glucose-1-phosphate‚ 1% maltose‚ honey‚ 1% sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch‚ the result was the starch solution turned dark blue. Starch had a positive result is because of the complex of iodine stuck inside the amylase

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

Immobilized Enzyme Immobilized Enzyme * Enzymes which are attached to small bead made of alginate are called immobilized enzyme * However‚ whatever the nature of an immobilized enzyme‚ it must comprise two essential functions‚ namely the non-catalytic functions (NCF) that are designed to aid separation and the catalytic functions (CF) that are designed to convert the target compounds within the time and space desired * Immobilized enzymes might meet the increasing demand by manufacturers

scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose

The Rate of Reaction that Enzyme Concentration‚ pH‚ and Temperatures Have on the Amylase Enzymes Color Disappearance Abstract: Compare reaction rates of the concentrations‚ pH’s‚ and temperatures of the enzyme Amylase. At what concentrates do the substrate molecules collide with each other‚ making the reaction possible? At what pH levels do the 3D molecular structures change breaking the H-bond and/or denaturize? At what temperatures do the collisions of the substrate molecules happen

Starch/Amylase Experiment Report Objective: The purpose of the starch/amylase experiment was to simulate and observe the process of enzyme digestion. Materials: * 1 small beaker * 2 large beakers * 2 cut pieces of soaked dialysis tubing * 2 dialysis tubing clamps or pieces of twine * 2 clean plastic pipettes * 1 bottle of Lugol’s solution * 2 glucose test strips Procedure: Begin the experiment by placing 4 full pipettes worth of cooked starch in a beaker. Then‚ use
