Detailed explanation-1: -Amino acids are attached to other amino acids by covalent bonds, known as peptide bonds, which are formed by dehydration synthesis reactions. The carboxyl group of one amino acid and the amino group of the incoming amino acid combine, releasing a molecule of water and forming a peptide bond (Figure 3.7).

Detailed explanation-2: -Dehydration synthesis is the creation of larger molecules from smaller monomers where a water molecule is released. This can be used in the creation of synthetic polymers such as polyethylene terephthalate (PET), or the creation of large biological molecules such as carbohydrate polymers and triglycerides.

Detailed explanation-3: -During dehydration synthesis, either the hydrogen of one monomer combines with the hydroxyl group of another monomer releasing a molecule of water, or two hydrogens from one monomer combine with one oxygen from the other monomer releasing a molecule of water.

Detailed explanation-4: -Peptide bonds are formed as two amino acids are joined together to form a protein. Peptide bonds form through a process called dehydration synthesis (polymerization). Polymerization is a process in which monomers are joined together to form polymers.
