Amino acids are the fundamental building blocks of all proteins. Often times scientists may need to identify the amino acid contained in a protein. One such method for separating and identifying individual amino acids is paper chromatography. In this activity, students will perform a paper chromatography experiment on three known amino acids, and then use their results to identify the components of an unknown amino acid mixture. This kit contains enough material for 5 groups. Teacher’s Manual and Student Study Guide copymasters are included.
