Detailed explanation-1: -peptide bond. Amino acids can be linked by a condensation reaction in which an ―OH is lost from the carboxyl group of one amino acid along with a hydrogen from the amino group of a second, forming a molecule of water and leaving the two amino acids linked via an amide-called, in this case, a peptide bond.

Detailed explanation-2: -When two amino acids combine in a condensation reaction, a covalent bond forms between the carboxyl carbon of one amino acid and the amine nitrogen of the second amino acid. A molecule of water is then removed as a second product. Figure 5.3. 1: Amino acids join together to form a molecule called a dipeptide.

Detailed explanation-3: -Proteins are condensation polymers made from amino acids.

Detailed explanation-4: -During digestion, enzymes in our bodies break the proteins we eat down into amino acids (by hydrolysis). These amino acids are transported around the body by blood. In the bloodstream, condensation reactions build the amino acids up to produce proteins required by the body.
