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.
This type of bond is called a nonpolar covalent bond. A nonpolar covalent bond is one in which the sharing of bonding electrons is equal. When two atoms involved in a cova1ent bond are not identical (atoms of different. electronegativities) the atom that has higher electronegativity attracts the electrons more.
