Detailed explanation-1: -Peptide synthesis occurs when two amino acids are coupled together by a peptide bond. Peptide bond formation occurs by a process called dehydration synthesis. A peptide bond is a covalent bond that links amino acids together to form a polypeptide. A peptide bond is formed through a process called dehydration synthesis.

Detailed explanation-2: -Dehydration synthesis reaction (removal of a water molecule) links amino acids link together to form chains called polypeptides. Polypeptide chains join to form proteins.

Detailed explanation-3: -Condensation/ Dehydration Synthesis (removal of a water molecule) links amino acids together to form chains called polypeptides. Polypeptide chains join to form proteins. The bonds holding amino acids to each other are known as peptide bonds.

Detailed explanation-4: -The two joined amino acids are called a dipeptide. The amide bond is synthesized when the carboxyl group of one amino acid molecule reacts with the amino group of the other amino acid molecule, causing the release of a molecule of water (H2O), hence the process is a dehydration synthesis reaction.

Detailed explanation-5: -Polypeptide chains are formed by dehydration between the amino group of a L-amino acid4 with the carboxyl group of another. One hundred or more amino acids are linked together with covalent peptide bonds in various specific sequences in the polypeptide chain with polypeptide chains combining to form a protein.
