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 The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”

Detailed explanation-3: -A peptide bond is formed by a dehydration synthesis or reaction at a molecular level. This reaction is also known as a condensation reaction which usually occurs between amino acids. As depicted in the figure given below, two amino acids bond together to form a peptide bond by the dehydration synthesis.

Detailed explanation-4: -Disaccharides. Disaccharides (di-= “two”) form when two monosaccharides join together via a dehydration reaction, also known as a condensation reaction or dehydration synthesis.
