Valerie Henderson 10-1-07 How Much Protein is in your Favorite Drink? Abstract: Proteins are a very important organic molecule to the functions of life. They are made up of amino acids and contain carbon, hydrogen, oxygen and nitrogen atoms. The proteins differ by their R-group, which is the side chain that can be as simple as a hydrogen atom or as complex as a carbon skeleton. In the experiment, we found the amount of absorption of dilutions at different concentrations of protein levels. We read gel electrophoresis cards to with a known molecular marker to determine the types of other unknown proteins. The standard protein curve showed that the higher the concentration of protein, the higher the absorbance of the protein by the dilution. The gel electrophoresis showed the heavier proteins move slower down the gel and lighter proteins move faster down the gel. Introduction: Proteins are central to almost every form of life. Proteins are 50% of dry mass of most cells and instrumental in everything organisms do. Proteins play a role in structural support, storage, transport, cellular communications, movement, and defense against foreign substances. Enzymes are types of proteins used as catalysts to speed up chemical
