1.Key Concepts for Structural Elucidation Question 1. To identify: Type of reaction Functional group present in reactant and product Special structure present Gases or ppt Key Concepts for Amino Acids and Proteins 1. Properties of amino acids particularly the assignment of given pKa values of the fully protonated form (and if they will be deprotonated at pH of environments). 2. Electrophoresis to separate amino acids based on | charge / mass |. 3. Application to titration curves of amino acids.
