Concept #1: Memorizing Charged Amino Acids
Concept #2: Negatively Charged Amino Acids
Concept #3: Positively Charged Amino Acids
Concept #4: Grouping Charged Amino Acids as Acids or Bases
Practice: Draw in the R-groups from memory for each of the charged amino acids at physiological pH.
Practice: Fill-in the missing R-groups for the following peptide from memory: H-E-K. Circle the acidic amino acids.
Practice: Which of the following amino acids does not have a basic R-group?
Practice: Circle all the following amino acids with a basic R-group?
