Give an example of such an amino acid and a protein in which it occurs.Which of the following statements is true about amino acids? a. All twenty (20) of these protein-derived amino acids are a-amino acids, meaning that the amino group is located on the carbon alpha to the carboxyl group. b. For nineteen (19) of the twenty (20) amino acids, the a-amino group is primary. Glycine is different; its a-amino group is secondary. c.
