Final answer:
DCC is an organic chemical compound commonly used in peptide synthesis to form peptide bonds between amino acids.
Step-by-step explanation:
DCC (dicyclohexyl carbodiimide) is an organic chemical compound used in peptide synthesis. It plays a crucial role in linking amino acids together to form a peptide chain. By activating carboxyl groups in the presence of DCC, peptide bonds can be formed. For example, when DCC is used in the synthesis of a dipeptide, it reacts with the carboxyl group of one amino acid and the amino group of another amino acid, resulting in the formation of a peptide bond between them.
