The correct answer is- It connects amino acids.

Peptide bond is formed between two amino acids during protein synthesis. It is a bond between amino group (-NH2) of one amino acid and the carboxylic group (-COOH) of another amino acid, releasing a molecule of water.

Thus, during protein synthesis, peptide bond serves the purpose of connecting or linking amino acids together.
