Hydrogen bonds, as well as the other types of noncovalent interactions, are very important in terms of the binding of a ligand to a protein. In section 1.3, we saw a 'space-filling' picture of an enzyme with its substrate bound in its active site.
Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds.Nonpolar covalent bonds.1  A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair.onds that are partly ionic are called polar covalent bonds.
