Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

During all this‚ concentration camps were being made. A concentration camp is a place where large numbers of people‚ especially political prisoners or persecuted members of a minority‚ are imprisoned in a small area with inadequate facilities‚ sometimes to provide forced labor or to await mass execution. Many of these concentration camps later became death camps for Jews. One of the most infamous concentration camps was Auschwitz because it was the largest of all concentration camps. In these

EXERCISE 3: DIFFERENTIAL PROTEIN PRECIPITATION Vanessa Andrea Estepa University of Mindanao‚ College of Science and Mathematics ABSTRACT: Denaturation is the disruption in the original conformation of the protein wherein the secondary‚ tertiary and quaternary structures are all affected. Denaturation is brought about by various kinds of physical and chemical means; this includes the addition of strong acids‚ heavy metal cations‚ alkaloidal reagents‚ salting out and addition of organic solvents.

EXTRACTION AND ISOLATION OF PROTEINS Background of the experiment Pure proteins are not readily available for study or use. There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many possible sources where we could get proteins. It can be from plants

Give an account of protein structure and function Protein structure 1 Proteins consist of amino acids joined together (in chains) 2 A protein is unique because of the sequence of amino acids 3 The amino acids are joined by strong peptide bonds 4 to produce the primary structure 5 Further (weak) hydrogen bonding between acids 6 produce the secondary and tertiary structures A maximum of 4 marks can be gained from this section.

Concentration Camps There were many social‚ political‚ and economic causes of WWII. A political cause was the treaty of Versailles. The treaty of Versailles was when we forced Germany to take the blame for WWI. If they didn’t sign the treaty‚ Germany would face invasion. As Germany did not start WWI‚ they felt it was unfair. An economic cause of WWII was the Great Depression. The Great Depression happened world wide. The Great Depression started with the stock market crash. The stock market crash

The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

Concentration Camps Sydney Quarantillo Grand Island Senior High School “The Holocaust illustrates the consequences of prejudice‚ racism and stereotyping on a society. It forces us to examine the responsibilities of citizenship and confront the powerful Ratification’s of indifference and inaction” said Tim Holden. The holocaust is something worldwide that will never be forgotten and cannot be erased from history. To understand the holocaust learning about Adolf Hitler

Level 2 2010/11 ‘Seller concentration levels are of interest on both theoretical and public policy grounds’. Discuss. Market structure plays an important role in any industry. Examining the market structure is essential for firms to perform well and behave rationally. The key characteristics of market structure include the number and size of firms‚ the existence and height barriers to entry and exit‚ and the degree of product differentiation. Seller concentration refers to the number and level

discuss how concentration ratios are used to determine total market shares within four specific industries. I will also discuss the levels of competition within those industries and how oligopolies can benefit society. Case‚ Fare‚ and Oster defines concentration ratio as the share of industry output in sales or employment accounted for by the top firms (2009). They are used to measure the total output produced by a certain number of firms within an industry. Four-firm concentration ratios
