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 on

conditions the coagulation process may be reversible. (Campbell‚ et.al‚ 1979) 4A.2.2 Chemistry behind Coagulation Ovalbumin the main protein in egg white is a globular protein denatured by heat‚ this means reaction is more rapid with an increase in temperature of heating. Since heat is absorbed during coagulation of egg proteins‚ the reaction is endothermic. Egg white coagulated by heat changes from a transparent viscous solution to a opaque white gel‚ the water of white trapped by the protein. (De Mann

Sperm starts within the testis‚ in which it then passes into the epididymis and sits until it matures in the few days that it had waited. Then‚ the sperm is forced up into the ducts (vas deferens) into the seminal tubule and into the ejaculatory ducts‚ which moves semen into the urethra. Once that occurs‚ the semen covers the sperm and it moves into

testing procedures for two large‚ organic molecules: proteins and starches. Hypothesis: In the test for protiens the water‚ being that it is inorganic will not test positive for protiens; it will serve as the negative control. The milk and 50% egg solution should test positive for protien as they are subsatnce derived from animals which contain protiens in order to carry the functions of life. The sucrose will test negative due to the fact that it is a carbohydrate and not a composition of organic

proteins. It will also include the knowledge of how these macromolecules function in living organisms. This experiment will identify the macromolecules with the use of test substances to identify each. In my first experiment to test for proteins the egg white with the Bluret reagent should come out positive for being a protein. The pepsin in the Bluret reagent should be positive and should be a protein. The test for sugar in the Bluret reagent should be negative and I don’t think it is a protein

If the water is a hypotonic solution‚ then the egg will swell.

I enjoyed reading Chairman Mao is a Rotten Egg because it shows the relationship between parents and children and parents and the government under Mao Tse-tung. The mother in the story was very concerned with what she thought her child said because it had potential to jeopardize her relationship or right standing with the government. If her child‚ Ching-Ching‚ was a counterrevolutionary‚ there was a possibility that he would have been killed or at the least had his statement on record for the rest
