By y.c.pong Introduction: When you heat an egg‚ the egg white clump together and turned white. It is because the protein in egg white undergoes denaturation‚ the cross linkage(the hydrogen bonds‚ ionic bonds and disulphride bonds) which maintain the protein shape destructed‚ so protein lose its tertiary conformation. This denaturing process is very important‚ because before protein can be used in digestion they must be unfolded. Part A: denaturation of egg white Aim: To examine the factors

How a Microwave Works By Zach Betten [pic] What is a Microwave? A microwave oven or microwave is a kitchen appliance that cooks or heats food by using electromagnetic waves. This happens by using microwave radiation to heat materials such as water and other things within the food. This leads to food being more evenly heated throughout. Basic microwave ovens heat food quickly and efficiently. One setback is that they do not brown or bake food in

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. Protein function 7 Some proteins are enzymes + named example

Due Date: February 1st School: Lake Arbor Elementary School Grade: 6th Teacher: Mr.Debaun Problem: How can I make an egg bounce? Hypothesis- I think the hard-boiled egg is more likely to bounce because it is soft once you finish cooking it and the raw egg will be hard cause of the shell on it “How to Make an Egg Bounce” By Daija Warren Lake Arbor Elementary School February 1‚ 2011 I would like to thank my mom with helping me with my science

High Protein Diets: Good or Bad? Lose weight while feasting on steak‚ burgers‚ cheese‚ and bacon? All without feeling hungry? What’s not to love? Meat lovers have flocked to high-protein‚ low-carb plans like Atkins‚ Zone‚ Protein Power‚ and Sugar Busters. While these diets can work‚ you need to carefully consider the risks and rewards before deciding if one is right for you. How Much Protein? Most Americans get 12%-18% of their calories from protein. With a high-protein diet‚ it can be much

reality was not as fantastic as he had imagined. In “Bumping into Mr. Ravioli‚” Gopnik uses his daughter Olivia and her imaginary playmate Charlie Ravioli‚ who is always too busy to play with her‚ to reveal a deeper truth about New York. Gopnik explains how imagination can be beneficial in understanding reality. Gopnik and Winterson both confirm that imagination is beneficial because it can help individuals to develop their identity and to have fun. One the contrary Gopnik contradicts Winterson‚ suggesting

17.1 Genes specify proteins via transcription and translation * George Beadle and Edward Tatum worked together with mutated (Neurospora crass) bread mold to figure out that they were missing a specific enzyme (gene) that catalyzed and synthesized a pathway required. They concluded that they were missing that enzyme because it was lacking the amino acid that coded for the enzyme‚ thus was mutated and incapable of growing. Led to the one enzyme-one gene hypothesis. The Products of Gene Expression:

Where ’s the Protein? Proteins‚ which are constructed from amino acid monomers‚ are considered one of the four major macronutrients needed by the body‚ along with carbohydrates‚ lipids‚ and nucleic acids. Only the first three nutrients listed require delicate balancing. One must consider the sources from which he or she receives those required nutrients. Carbohydrates from fruits‚ vegetables‚ and grains; lipids from oily animals such as fish or plant foods like avocados; and proteins from meats‚

CHARACTERIZATION OF PROTEINS Abstract Different techniques and principles for protein extraction and characterization were demonstrated in this experiment. Various proteins were extracted from different sources: 1.67 g yeast invertase‚ 1.03 g egg white albumin‚ and 5.15 g of milk casein. Activity assay for invertase was performed using Benedict’s test and the enzymes inverting action on sucrose was confirmed. Warburg-Christian Method and Bradford Assay were also employed to determine the protein concentration
