• Abstract Hydrolyzed Protein is protein that has been hydrolyzed or broken down into its component amino acids. While there are many means of achieving this, two of the most common are prolonged boiling in a strong acid (acid-HVP) or strong base or using an enzyme such as the pancreatic protease enzyme to stimulate the naturally-occurring hydrolytic process. A series of tests were performed and yielded positive results for each of the protein hydrolysis.
• Introduction
Proteins, from the Greek proteios, meaning first, are a class of organic compounds which are present in and vital to every living cell. In the form of skin, hair, callus, cartilage, muscles, tendons and ligaments, proteins hold together, protect, and provide structure to the body of a multicelled organism. In the form of enzymes, hormones, antibodies, and globulins, they catalyze, regulate, and protect the body chemistry. In the form of hemoglobin, myoglobin and various lipoproteins, they affect the transport of oxygen and other substances within an organism.
The total protein component of milk is composed of numerous specific proteins. The primary group of milk proteins are the caseins. There are 3 or 4 caseins in the milk of most species; the different caseins are distinct molecules but are similar in structure. All other proteins found in milk are grouped together under the name of whey proteins. The major whey proteins in cow milk are beta-lactoglobulin and alpha-lactalbumin. The major milk proteins, including the caseins, ß-lactoglobulin and a-lactalbumin, are synthesized in the mammary epithelial cells and are only produced by the mammary gland. The immunoglobulin and serum albumin in milk are not synthesized by the epithelial cells. Instead, they are

    In the second separation of this experiment, the Erlenmeyer flask with the first filtrate was put into a beaker so the filtrate was in the beaker. The beaker was then heated on a hotplate until near boiling. After the whey protein had precipitated, a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again, a small test tube was used and 2 mL of protein test solution was put in the tube. Five drops of 10% NaOH and 2 drops of 0.5% CuSO4 were added to this tube. If a purple color showed, it would indicate there was protein in the test tube.…

    Hydrolysis Report

    • 1525 Words
    • 7 Pages

    Hydrolysis is a chemical reaction that uses water to split complex molecules. The water molecule H2O is split in the mechanism of hydrolysis, hydrogen cations and hydroxide anions. When the enzyme catalyzes its reaction inside the cell, it is referred to as intracellular hydrolases. When the enzymes secreted from the organism to catalyze reactions outside the cell, it is referred to as exoenzymes or extracellular hydrolases. Four hydrolysis reactions are discussed in the report, bile esculin hydrolysis, starch hydrolysis, urea hydrolysis and casein hydrolysis. Bile esculin hydrolysis determines whether an organism is able to hydrolyze the glycoside esculin. Starch Hydrolysis identifies organisms that can hydrolyze starch. Urea hydrolysis tests for the ability of organisms to hydrolyze urea via the intracellular enzyme urease. Casein hydrolysis tests for organisms capable of hydrolyzing casein via the casease.…

    Hydrolysis of Macromolecules

    • 2412 Words
    • 10 Pages

    This lab was designed to teach the process of “hydrolysis”, a chemical reaction in which water is added to a polymer, breaking its bonds and forming smaller molecules. A hydrogen cation and a hydroxide anion (which once formed water) break apart and attach themselves to the ends of shorter polymers. Hydrolysis plays an important role in our lives and in the lives of every living thing on earth. Living organisms rely on digestion (hydrolysis) to convert food energy from polymers into monomers, which are easier for our cells to absorb. This study was conducted to show how polysaccharides are broken down by organisms to absorb nutrients through hydrolysis. We used different methods to show how different tests involving heat, acid, saliva, and bacteria can hydrolyze polysaccharides and proteins.…
