identify an unknown amino acid. IntroductionAmino acids are simple monomers which are strung together to form proteins. Amino acids play a key cellular role in structure and function. Proteins themselves participate in nearly every physiological event in the cell. Since all amino acids contain at least one amino and one carboxyl group‚ they are classified as amphoteric substances (meaning that they can act as either an acid or as a base) (1). Treating the zwitterion with acid will result an addition

which four amino acids‚ histidine‚ lysine‚ glutamine‚ and glutamic acid‚ are identified based on their titration behavior. Solutions of each unknown amino acid are made and the change in pH upon adding small amounts of NaOH aliquots of a strong base are monitored. The amino acids are identified using the information represented by the titration curves. The titration curves include the following information: isoelectric points‚ pKas‚ buffering regions and the structures of the amino acids. The results

less than that of the reaction rate at a neutral and slightly basic pH environment. This finding partially supports our hypothesis. The spectrophotometer readings in our experiment measured the absorbance of 3-amino-5-nitrosalicylic acid‚ a colored molecule formed after dinitrosalicylic acid (DNSA) has reacted with the products of the enzymatic reaction or the simple sugars. Therefore‚ the absorbance readings correspond to the concentration of the simple sugars produced by the reaction. In the end

DNA DNA‚ or Deoxyribonucleic Acid‚ is described‚ in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus‚ passing on the information needed for protein synthesis. In most cellular
