Detailed explanation-1: -Dehydration synthesis is a key step in the formation of polymers, large molecule chains formed by linking together multiple monomer units (via dehydration, of course). In biology, dehydration synthesis forms large polymers commonly referred to as biological macromolecules.

Detailed explanation-2: -Each amino acid is delivered to the ribosome by a transfer RNA? molecule depending on the code in the messenger RNA. These amino acids are added in sequence to form a chain of amino acids. After the last amino acid is added to the chain, it folds up to form the final protein.

Detailed explanation-3: -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-4: -Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding.
