Denaturing of Proteins Research Paper

Abstract:

Introduction

The experiments the objective is to determine, the possible measures of the denaturation process of several proteins by using a home based temperate The necessary applications of this experiment are to compile all the possible measures of the denaturation process in understandable units and explainable means. Other methods possible for research are by using a method that was used in this experiment is scientifically logical due to the fact that it can be done easily and at a low cost while producing sound and replicable data. All in all the experiment is able to produce data that is obtained simplistically while being applicable to the scientific community. The process of denaturation is very simple when carried out skillfully and carefully. When a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denatured protein has the same primary structure as the original, or native, protein. The weak forces between charged groups and the weaker forces of mutual attraction of nonpolar groups are disrupted at elevated temperatures, however; as a result, the tertiary structure of the protein is lost. In some instances the original structure of the protein can be regenerated; the process is called renaturation. (Haurowitz Felix, 2013)
Changing the conformation of a protein either temporarily or permanently by disrupting these forces is called denaturation. Denaturation results in a loss of activity. Since the native conformation is usually the most water soluble, disrupting the secondary and tertiary structures causes changes in solubility and frequently results in precipitation of the protein from solution. Reagents or conditions that can cause denaturation are called denaturing agents; these include heat, pH

    The graph was about turbidity reading at different temperatures at 340nm. The curve of egg white in the graph increased dramatically at first. At 80℃, the curve got a peak at 0.251. The peak was where the protein was fully denatured. Then, the curve dropped quickly. With the raising of the temperature, protein in the solution got denatured. When the temperature increased from 60℃ to 80℃, the structure of protein got unfold. When the solution was heated, the H-bond was broken. The hydrophobic parts of protein were inside the protein surrounded by hydrophilic parts before unfolding. With the temperature increasing, the hydrophobic parts were exposed. The hydrophobic parts of proteins interacted. The reason why the turbidity reading got bigger is that protein unfold and the unfold proteins got coagulation. The coagulation caused the turbidity of solution increasing. The melting temperature of the native egg white sample was at the half of denaturation. It is about 71℃. The curve dropped because coagulation floated to the surface of solution. The curve of succinylated egg white did not change much. The –NH3+ of protein in egg white was replaced by COO- at pH8, so the protein was negative charged. The fastest coagulation of protein is at pI (isoelectric point). Because the pH of solution was at pI, the whole process is slow.…

    If the temperature of the enzyme is heated or cooled, then the time for the reaction to take place will increase or decrease. I think this will happen because if the enzyme is exposed to cold temperatures, its reaction (in this case denaturisation) will occur at a slower rate as the molecules move very slowly under these conditions. If the enzyme is heated, then the denaturisation may occur at a faster rate as the molecules move more quickly in the enzyme. Therefore, the results of this lab will be dependent on the temperature that the enzyme is exposed to in determining how long it takes for the enzyme to…

    HypothesisIt was predicted that the physical characteristics of the egg white solution at room temperature would appear clear and normal like a raw egg white. This is because nothing would be done to the egg white. It was also predicted that when the egg white solution gets heated, the protein would denature if the temperature exceeds 65 °C. The protein would solidify, turn opaque, and turn white in colour. This would happen because the heat at a certain temperature will cause the amino acids in the protein to unravel, thus the protein would lose its structure, and this would reveal a colour change. It was also predicted that when acid is poured into the egg white solution, the proteins would denature and turn into a white colour. This would be because it would result in a further straightening effect on the protein chain. It was also predicted that when silver nitrate is poured into the egg white solution, it would result in some sort of precipitate since silver is always precipitating out. Also, since salts are ionic compounds, they disrupt salt bridges in proteins, and so this can also be a factor.…

    Protein Texturization

    Proteins are responsible for the distinct physical structure of a number of foods such as fibrous structure of muscle tissue like fish and meat, the porous structure of bread and the gel structure of some dairy and soy products. Although many plant proteins have a globular structure are available in large amounts, however, they are used only a limited extent in food processing. To transform a fibre-like structure of protein to globular proteins, protein texturization is used to process a protein product with cooking strength and a meat-like structure. This type of product is marketed as spun protein isolates, formed meat analogs, extrusion cooked meat extenders and meat analogs. ( H.D.Belitz,W.Grosch,P.Schieberle, 2009)…
