Regarding the strategy of peptide synthesis, which statement is true?

Question

Quizplus · Accepted Answer

In peptide synthesis, the N-terminal amino acid is often protected using a t-BOC group (A). The N-protected amino acid is activated using DCCD (B) to form an active ester, facilitating peptide bond formation. The reaction between amino acids proceeds via nucleophilic acyl substitution (C). Removing the protecting group allows further reactions to proceed, driving the synthesis to completion (D).
