Endoamylases cleave the,1-4 glycosidic bonds present in the inner part of the amylose or amylopectin chain. Serial Dilution Lab Conclusion Professional Areas IncludingLab reports can also be written for college classes, as well as other professional areas including engineering and computer sciences. A lab report typically includes all of the following sections in the same order. Sometimes acknowledgments are skipped in less formal reports that are written for a college class. In addition, the introduction and abstract are sometimes merged into one section in a college setting. A bad, vague, example would be Influence of various factors on amylase activity. Remember to use a past-tense and passive voice throughout the entire lab report. Activity was measured by measuring the rate of disappearance of starch using I 2 KI, a color changing indicator that becomes purple in the presence of starch. The results suggest that as concentration of amylase decreases, the rate of starch digestion decreases. Similarly with pH, as it deviates away from 6.8, the rate of starch digestion decreases. Finally, the rate of starch digestion decreases as it deviates from the ideal body temperature of 37C. Essentially you are introducing a reader to your topic and its background. You are also writing a hypothesis and telling your reader what that hypothesis is. An assay is usually performed to determine this type of information. The rate of a reaction depends on more factors than the three examined. In addition to temperature, pH, and concentration other factors such as the structure of the substrate, the amount of concentration of the substrate, the ionic strength of the solution, and the presence of other molecules that can act as activators or inhibitors 1.For the factors that were examined it was predicted that as amylase concentration decreases the enzyme function decreases as measured by the rate of starch digestion. For pH it was predicted that as it deviates from 6.8, the ideal pH for amylase to function, the activity of the enzyme decreases. Lastly, for temperature it was predicted that as the temperature fluctuates away from 37C either higher or lower, amylase activity will also decrease. The effect of concentration, pH, and temperature on amylase were examined to determine how these factors affect enzyme activity. The importance of enzyme inhibition was studied in an experiment in which Inhibition of starch digestion by alpha-amylase inhibitor reduced the efficiency of utilization of dietary proteins and lipids and slowed the growth of rats. The study saw that at the two highest levels of amylase-inhibitor 3.3 and 6.6 gkg diet, the growth rate of rats and apparent digestibility and utilization of starch and protein, was significantly less than in control rats 2. The mechanisms for starch digestion of amylase depend on the class of the amylase enzyme. There are four groups of starch-converting enzymes: (i) endoamylases; (ii) exoamylases; (iii) debranching enzymes; and (iv) transferases.
