Covalent Bond

The sharing of two or more electrons between two atoms.

Among chemical bonds as found within bodies, Covalent Bonds are among the strongest, particularly as found within aqueous solutions and other than in terms of those non-covalent chemical bonds found within crystalline structures such as tooth enamel.

In terms of strength of chemical bonds, diamonds, for example, are held together entirely by covalent bonds between carbon atoms.

So too are carbohydrates, lipids, nucleic acids (but not including the hydrogen bonds holding together the individual strands of nucleic acids making up double helices), and the polypeptides making up proteins held together as molecules by covalent bonds.

See by contrast ionic bond, hydrogen bonding, and van der Waals interactions. See also polar covalent bonds and nonpolar covalent bonds.
