QUALITATIVE ANALYSIS OF PROTEIN AND AMINO ACIDS

This kit demonstrates the principles of protein and amino acid analysis and enables students to identify unknown compounds. In this set of lab activities, students work with the proteins, albumin and gelatin, as well as the amino acids, glutamic acid, glycine, cystine, cysteine, tyrosine, tryptophan, and arginine. Ninhydrin is used to detect the presence of amines, indicating the presence of amino acids and/or proteins, the Biuret test is used to detect the presence of peptide bonds, and specific analytical tests are used for determining the presence of individual amino acids. Protein and amino acid analysis techniques are an integral part of biochemistry and the range of tests available for analyzing amino acids and proteins are indicative of their importance. Required, but not included: concentrated nitric acid, ethanol, hot plates, balances, glassware, and distilled water. Designed for 24 students working in six groups of four.
Grades 10-14
