iodine can be measured by using a spectrophotometer. α-amylases are found in saliva‚ pancreatic juice‚ human breast milk‚ serum and certain tissues such as the liver. This enzyme catalyzes the hydrolysis of α (1-4) linkages in starch by breaking it down to maltose and some glucose. As the starch is broken down‚ the coiled structure of α-amylase is unfolded. Therefore‚ iodine will no longer be able to form the blue complex with the α-amylase. It can be assumed that the decrease in color (absorbance)

of a reaction. Each enzyme binds closely to the substrate; this greatly increases the reaction rate of the bounded substrate. Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2) the environmental factors that can affect the enzymatic activity. The hypothesis‚ in relation to the

Dear Alpha Kappa Alpha Sorority‚ Incorporated In Today’s society the black woman is looked at as objects with bad attitudes. For example‚ shows like Love&Hip Hop‚ Basketball Wives‚ and Bad girls Club do not help the image of the black female any better.

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

Period 12 Chemical Aspects of Life & Spit Lab ABSTRACT: The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence

The Cronbach Alpha Reliability analysis has been used and the Cronbach Alpha coefficient generated by SPSS gives an evaluation of the consistency. Generally‚ if a Cronbach Alpha coefficient of fewer than 0.60 is obtained‚ the internal consistency is assumed to be poor; a value in the range of 0.60 to 0.80 is suitable consistency and values above
