Answer:
Peptide bonds are formed by hydrolysis or losing a water (H₂O)
Explanation:
Two or more amino acids are linked by forming peptide bonds, and then eventually form polypeptides. These peptide bonds are <u>covalent </u>in nature and require water. an amino group and a carboxyl group to form. These components then undergo hydrolysis to form long-chain amino acids.
The sequence of the amino acid chain <u>starts with the α-amino group residue and with an α-carboxyl group as the terminal residue</u>. This chain is also known as the primary structure of the protein molecule.
While observing through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells. Hookes discovery led to the understanding of cells as the smallest units of life—the foundation of cell theory
