four food apple sauce, carrot juice, cracker juice, and turkey juice contain protein, starch, or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive for protein and it is the turkey juice. Introduction The “Food Lab” was used to answer…
Results Calculation a) 50ml of suspensions containing 5% w/v of sulpharmerazine which containing 10-2, 5 x 10-3, 10-3, 5 x 10-4, 10-4, 5x 10-5, and 10-5 molar concentrations of Calcium Chloride. ( 10-2 are provided ). By using this formula, we can get the amount of calcium chloride to be added in making 50 ml suspensions containing 5% w/v of sulpharmerazine. M1V1 = M2V2 M2 = 5 x 10-3, 10-3, 5 x 10-4, 10-4, 5x 10-5, and 10-5 M , V2 = 50ml M1 = 0.01M Thus, V1 = ( M2 . V2 )…
Brittney Humphries. Title: Testing for the Presence of Starches, and Proteins Purpose: To test for the presence of starches and protein macromolecules, to introduce the concept of variations in chemical compounds. Hypothesis: If biuret is blue after a test for protein, then it is a negative result because biuret reagent is blue to begin with. If a solution is pinkish purple, or purple, then the test for protein is positive. The test solution for starches is yellowish brown. If any substance…
Testing for reducing sugars, non-reducing sugars, starch, lipids and proteins in unknown substances: Our aim: was to find out which substances from our five samples have reducing sugars present to determine what they may be for example; they could be monosacchrides or disaccharides. This was carried out by using Benedict’s test. To find out which substances from our five samples were non-reducing sugars, since some disaccharides are reducing sugars and this would be carried out by using Benedict’s…
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…
SUSPENSION SYSTEM FUNCTIONS OF SUSPENSION SYSTEMS: To provide good ride and handling performance – –providing chassis isolation –ensuring that the wheels follow the road profile –very little tire load fluctuation To ensure that steering control is maintained during manoeuvring – –wheels to be maintained in the proper position wrt road surface To ensure that the vehicle responds favourably to control forces produced by the tires during –longitudinal braking –accelerating forces…
Rethinking Fantasy And The Suspension Of Judgment: A Reflexion On Critical Skills, Themes And Issues The suspension of judgement as a critical skill is a vital part in the interpretation of works of “fantasy” which also suggests the transformation of the concept of “fantasy” itself into something more than the conventional notion of the Western cultural tradition. In the critical analysis of works of “fantasy”, foregoing the suspension of judgment would mean the awkward assumption of the conventional…
“Is Starch Permeable in Cells? Abstract This report presents the weights of 3 samples of water with various amounts of solute after the use of osmosis. Three different tests were performed, each with a beaker of water containing varying amounts of starch from 30% concentration (12.5 grams of water) to 15% concentration (9.5 grams of water), and then 0% (10.5 grams of water). To start this experiment, we put water into a make-shift dialysis tube, a type of semi-permeable membrane tubing made…
Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato, which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test for the presence of starch, the Starch Test is used…
Introduction: In this lab i used glucose and starch to show if the cell membrane is permeable, impermeable, or selectively permeable to these substances. Dialysis tubing is a plastic like substance that has small pores in it. These pores allow certain chemicals to flow into and out of the cells. The size of the molecule determines what goes through the tubing. On of the materials that we will be using is glucose. glucose is a simple sugar that easily dissolves in water. To test for the presence of…
