Cynthia Vang Derrick 24 Title: Digestion of Starch Problem: Hypothesis: If synthetic saliva breaks down the cracker the most Then more of the cracker should be digested Because synthetic saliva contains amylase‚ and amylase helps break down complex carbohydrates. Interpretation: Data Table: The results of the iodine and Benedict’s tests for the Carbohydrate lab Test Tube contents and number Color of iodine test Color of Benedict’s test How much is present? 0= none 1= present How

Dialysis of starch‚ glucose and sucrose Introduction: Research question: Does the dialysis tube only allow certain substances to pass through the pores because of their size? Dependent and Independent variables: Independent variables: The temperature of the classroom The size of the molecules The size of the pores in the tube The concentration of the indicators Dependent variables: The substance will either pass the pores of the tube or not The result will vary in darkness (color) Controlled

· Alpha-1 level test – determines the amount of Alpha-1 Antitrypsin in a persons’ blood. To confirm the severity of the disease other tests may be done such as‚ chest x-rays and Computerized Automatic Tomography (CAT) scans. The chest x-ray examination may reveal a barrel-shaped chest. Also‚ listening to the chest with a stethoscope

bromide (polybrene) test in blood cross matching? Watch out! Abstract: BACKGROUND: Blood cross matching test mainly includes manual hexadimethrine bromide (polybrene) test (MPT) and the automatic analyzer method (by coombs card) at the Department of blood transfusion. Generally instrumental method is used for large quantities of samples. It can save manpower; MPT is used for emergency and few samples. it can save time. Our department recently encountered a case of cross match blood test by MPT was negative

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

It about modified starch Journal of Agricultural Science Vol. 2‚ No. 2‚ June 2010 requirements are properties such as viscosity‚ resistant to shear‚ low pH and high temperature. Accordingly‚ varieties of modified starches are used in food industry. Table 1 lists some of the modified starches that can be prepared from different sources to meet the marketing-related requirements. Today‚ modified food starch is a food additive and limits of its modification‚ use and labeling are clearly defined

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
