pills. Should you? In the United States today many people have supposedly lost weight with certain pills. One of these pills is called carb cutter. Carb Cutter claims to inhibit the activity of the starch-digesting enzyme‚ amylase. When the diet pill binds to the amylase‚ it prevents the breakdown of starch. In the Biology 1103 lab‚ we conducted two experiments to determine whether or not the diet pill‚ Carb Cutter‚ actually worked. In each experiment we used an experiment tube and a control (blank)

Scat by Carl Hiaasen (3rd person point of view) Scat is a mystery book‚ taking place in Florida‚ of a missing teacher named Mrs. Starch‚ and two of her students‚ Nick and Marta‚ do whatever they can to find her. The novel starts in biology class. A biology teacher‚ Mrs. Starch‚ asks a question about the Calvin cycle‚ which a girl named Libby wants to answer. Mrs. Starch is very strict and mean. Instead she calls on Smoke to answer the question‚ who then eats part of Mrs. Starch’s pencil. He then is

Natural Dyes from Plants in Producing Colored Paste Abstract: Paste is a type of glue made from starch or dextrin‚ a starch product. This investigatory project shows that we can produce our own colored paste without spending much time and money and by performing simple steps. That’s why this Science Investigatory Project can help students save their money instead of spending it in buying expensive and commercialized colored glue. In addition‚ this colored paste can be an additional source of

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

Protein or a Starch. It is my belief that only 1 or two of each of the substances in test 1( proteins) and test 2 (starch) will test positive for either protein or starch. For this lab the following materials were needed to complete the experiments in test 1 for proteins: Di water‚ ev milk‚ 50% egg solution‚ 1% sucrose‚ 4 test tubes‚ 1 test tube rate‚ safety glasses‚ pipets and the reagent solution. For test 2 for starches the following materials were used: Di water‚ 1% starch solution‚ onion

Experiment Objective(s): The reason for this experiment is to see how starch and iodine affect each other and how a plastic bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and they will both absorb relatively similar amounts
