B. Statement of the problem. General Problem The problem is if cassava starch is an effective component for biodegradable plastic. Specific problems The easiest problem to solve will be the texture and bubbles. The mixture can’t be too thick when it’s being made and heated. If it’s too thick‚ air bubbles will get trapped in the mixture when it’s heated and won’t be able to get out. Try adding more water. It will take longer to dry‚ of course‚ but that will help to get rid of the bubbles

The Effect and Rate of the Enzyme Amylase on Starch Abstract Assessing reaction speed of the enzyme amylase can be measured by the amount of glucose and maltose produced during given time intervals. I hypothesized that‚ if the reaction time is longer‚ then the amount of amylase will be larger. Enzymes are specific in their match of substrates they will breakdown – similar to a key and its lock. Since amylase is the only enzyme that breaks down starch‚ the procedure was effective and gave clear

orange juice is held in a test subject’s mouth‚ the greater the ability of the test subject’s saliva will become to break down starches. Dependent Variable: pH of the saliva. Independent Variable: time that the juice is swished in the mouth. Controlled Variables: Orange juice only. The amount of orange juice tested must be the same for every trial. A 1% starch solution must be used in every test tube. Identical iodine solutions must be used to test the starch solution. The temperature

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2]. A B Figure 1. Starch (amylose) (A) and cellulose (B) Starch occurs

Focused Question: How can one determine the presence of glucose‚ starch‚ lipid‚ and protein in various samples? Pre-lab Questions: • Glucose is a monosaccharide. What does this mean? A monosaccaride is a carbohydrate molecule with three to seven carbon atoms with the corresponding number of hydrogen and oxygen atoms. • Proteins are made of amino acids. What atom is present in an amino acid that is not present in a sugar molecule? One nitrogen atom is present per molecule in an amino acid

English III‚ period 4 Miss Streza January 28‚ 2014 In the novel Adventures of Huckleberry Finn by Mark Twain‚ satire pokes fun at the foundations of society. Twain uses satire to diminish society in ways such as education and slavery. Satire helps Twain create humor‚ irony and exaggeration throughout the novel. Education and slavery are used to help address Twains claim against society. When Twain describes slavery‚ he argues against the institution of slavery by humanizing Jim. “I

Bread contains starch. The starch content in bread is derived from the starchy endosperm of wheat. Refined breads have the bran and germ removed from the wheat in order to produce softer‚ silkier flour. there is a lot more food containing starch like: Starchy foods such as potatoes‚ bread‚ cereals‚ rice and pasta should make up about a third of the food you eat. Where you can‚ choose wholegrain varieties‚ or eat potatoes with their skins on for more fibre. Starch is the most common form of

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

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
