Product Details

General, Organic and Biological Chemistry What are the roles of amino acids in the structure and properties of proteins? Investigate proteins and amino acids and learn how these biological molecules can be identified. In this activity, students explore the structures and properties of amino acids and how they relate to protein function. Students perform chemical tests to detect the presence of specific amino acids and then determine the relationship between structure and function by studying protein denaturation. Complete for 24 students working in pairs.

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
