Amino acids are the fundamental building blocks of proteins. To learn which amino acids make up a given protein, scientists separate the amino acids using chromatography. Students will perform this same technique using three known amino acids and one unknown protein. By comparing the travel rate and distance of the amino acids, the composition of the protein can be ascertained. This kit contains enough material for up to 15 groups of students. Aligned to Next Generation Science Standards HS-PS1-3 and MS-PS1-2, and explores patterns as a cross cutting concept. In addition to the materials in the kit, a teacher's manual, student study guide copymasters, and material safety data sheets are included.
