DENATURATION OF PROTEINS Abstract The experiment was done to be able to understand how various denaturants such as HCl and NaOH affects proteins. It was observed that different denaturants act upon or denature protein differently. This was determined using the principle of viscometry. An Ostwald viscometer was used to measure the viscosity of the prepared native‚ blank‚ denatured native and blank with denaturant solutions. The time required for the said solutions to pass through the viscometer

Before I wrote this essay‚ I searched for images of excessive perspiration. During my search‚ I discovered there were various outlooks on the topic‚ but two prominent images caught my eye. One of the images feature a woman‚ who appears to be resting after a workout. The other image shows a man‚ who looks like he is taking a break from work. Both images illustrate different types of individuals with the same condition‚ but the first image would be considered more appealing than the other image. The

How the structure of proteins are related to their functions Rachel Morris The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve. There are 20 different amino acids and they can be joined in any order. Therefore there can be many different functions. A protein consists of one or more polypeptide chains (a polypeptide

Practical 3: Proteins Introduction: ‘Protein’ also an important food component‚ we commonly take in from our diet. In this experiment we have studied a certain property of protein‚ i.e.‚ protein can be denatured by various factors. A. Denaturation of egg white Results: Egg white sample in water baths | Test tube | temperature | Observations | 1 | 60°C | Took 7minutes and 15 seconds to turn white and form white participate. | 2 | 80°C | Took 2minutes and 20 seconds to turn white

The protein in consumed food turns into amino acid. The amino acid is used later replinish the proteins used. Proteins have two structures. the first and primary structure of protein is the sequence of the amino acid in the protein (Kim‚ 2005). The amino acid

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16‚ 2009 Introduction: In living cells‚ prokaryotic or eukaryotic‚ the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids‚ ribosomes‚ messenger RNA (mRNA)‚ and transfer RNA (tRNA)‚ are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell‚ and there are two
