Concept explainers
(a)
Interpretation: The name of given peptide using both the three-letter and one-letter abbreviations of the component amino acids is to be predicted.
Concept introduction: Peptide linkage is formed between the amino group of one amino acid and the carboxyl group of other amino acid with the loss of water molecule. Amino acids are naturally occurring compounds in which the amino group is present on the alpha carbon of carboxyl group. The name of amino acids is represented by the one-letter and three-letter abbreviations.
