WebWhen atoms are attracted to each other and join together to form a molecule, we call the connection between each atom a chemical bond. The bond “holds together” the atoms in the molecule, ion, or crystal. The bonds can often last indefinitely, until they are broken apart by an external force or energy. Chemical bonding is the attraction ... WebFeb 28, 2024 · Denaturation involves the breaking of many of the weak linkages, or bonds ( e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble.
