Most of the 20 standard amino acids are chiral, and most of the standard chiral amino acids have the S configuration at the alpha-Carbon (C-alpha). All of the standard chiral amino acids are L-amino acids. For the chiral standard amino acids, ribosomes only use the L enantiomer to make proteins. Which amino acids in the peptide shown below are NOT L-amino acids? (be sure to select 2 correct answers)
