Desizing Desizing is done in order to remove the size from the warp yarns of the woven fabrics.The sizing material present on the warp yarns can act as a resist towards dyes and chemicals in textile wet processing. It must‚ therefore‚ be removed before any subsequent wet processing of the fabric. Object: 1. To eliminate the water repellent nature of sized cloth. 2. To increase the absorbency. 3. To reduce the consumption

into 2 identical wells on the starch agar plate separately. Starch will be broken down by the amylase disused to the star-agar. A clean zone will be formed around the wells when iodine solution is added and flushed. The higher the amylase activity‚ the more the starch will be broken down. Hence‚ a larger and clearer zone will be observed. Thus the diameter of the clear zone can show the activity of the amylase. In this experiment‚ the independent variable is the types of washing powder in the solution

Front cover Aim Introduction Hypothesis Prediction Variables Materials Methods Results Discussion Conclusion Bibliography Aim The aim of the experiment is to see the enzyme amylase catalyse starch in a chemical reaction. | | Introduction Enzymes are proteins. They act as catalysts‚ allowing chemical reactions to take place by lowering the amount of energy needed. They therefore speed up a reaction without being

Observation #4 * When the solution was added to the hot water bath‚ the solution went from blue‚ to green‚ to yellow‚ and finally to orange as time progressed. This was a positive result‚ meaning that the amylase in our saliva broke the polysaccharides in the cracker into mono- and di- saccharides. As a result‚ the Benedict’s reagent changed colour because it indicated the presence of mono- and di- saccharides in the solution. Observation #5 There weren’t

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) tube. The purpose of a blank is to set a base level (zero) from which other measurements can be performed. In the first experiment we were trying to see if the amylase would digest the starch. We put amylase‚ TRIS

affect the rate at which starch hydrolyzed. In the experiment conducted‚ bacterium; Bacillus Licheniformis and the fungus; Aspergillus Oryzae was used to examine how changes in temperature of the enzymes affects the rate of the reaction with starch. Amylase is an enzyme‚ found chiefly in saliva and pancreatic fluid‚ that converts starch and glycogen into simple sugars. This enzymatic reaction therefore needs the utilization of water molecules. This is why the reaction is called a hydrolytic reaction

Experiment one had 108 piglets (28 days weaning) feeding on 0‚ 100‚ or 150 ppm enzyme complex. 6 pigs‚ at the end‚ from control and supplemented feeds were

damage to your cornea easier to see. Certain imaging test can check the function of your salivary glands. A sialogram is used to detect dye injected into the salivary glands located in front of the ears. This will show how much saliva flows into your mouth. A salivary scintigraphy uses an intravenous injection of radioactive isotope‚ which is track for an hour to show how quickly it arrives in the salivary glands. A lip biopsy may be needed to detect the presence of clusters of inflammatory
