In the human digestive tract, proteins are chemically dis night clubed down into smaller peptide units by the gastric juices in our stomachs. These gastric juices are strong unpleasantic solutions, which are composed of these digestive enzymes: hydrochloric unpleasant and pepsin. Pepsin is a digestive protease, which degrades proteins into peptides serving as the impulsion for the chemical digestion in the stomach.
In this experiment, the materials used were: egg albumin, a protein made from the egg whites, and distinct solutions varying at different acidities and alkalinities to test for protein digestion rates. Certain substances react with enzymes at an optimal pH at which the reactions occurs the fastest. Knowing that when a substrate is out of regularize with its optimal pH, the protein denatures, therefore decreasing the rate of reaction. The information gathered over a three-day period represents the rate of reactions in various(a) solutions. The results approve the hypothesis; that proteins in a solution of pepsin and hydrochloric acid will be digested the most for it is the composition of gastric acid in a humans stomach. To test the aptitude and rate in protein digestion, egg albumin was inserted into a looking glass tube and cooked.



Separating the egg albumin filled glass tubule into rough 3 cm, each were placed into their respective Metts underground containing various solutions involving a range of pH. Through a three-day period, the distance of the protein present before and after the experiment was recorded, to accumulate the results of how some(prenominal) egg albumin had been digested. This relation between pH and protein digestion apprize be represented by a graph created from our peaceful data. Through the knowledge of the acidity in the contents of the stomach, the data justifies our understanding of egg albumin digested through the course of a three-day time periodIf you want to get a full essay, order it on our website: Orderessay
