This paper reviews an experiment that aimed to isolate and partially purify the proteins ovalbumin, conalbumin, ovomucoid and lysozyme. Furthermore, the paper looks at how the study compares the efficiency of certain separation and purification methods and carries out biochemical tests and physicochemical characterization on the separated proteins. The paper outlines the methods and results and concludes with a summary of the study's findings. The paper includes graphs and tables.
From the Paper:"Human beings need a balanced diet of carbohydrates, proteins, fats and numerous other nutrients. Proteins are needed as part of a healthy balanced diet in order to sustain growth, provide structural support, boost the defences of the body and are involved in many vital body functions. Among the various sources of protein, one commonly consumed, rich source of such proteins is the eggs of the domestic fowl.
"The eggs of the domestic fowl consist of the egg white (albumen) and egg yolk. Egg albumen, which is the focus of this experiment, is a mixture composed of 88% water, 10% of different proteins and 2% of small quantities of carbohydrates, minerals and vitamins. Further focusing on the different kinds of proteins in egg white, the protein ovalbumin comprises of 54% of the protein percentage, and conalbumin consists of 12 % and ovomucoid, 11% and ovomucin, 3.5% and lysozyme, 3.5% and ovoglobulin, 8% and the rest of the 8% of various proteins. These proteins provide some biological benefits to the egg and to its consumers, which is why separating and studying these proteins and their special biochemical characteristics is very important."
