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.
Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals) An io â¦ nic compound is a pure substance that is formed from a metal and a nonmetal.here are two important types of covalent bonds: non-polar and polar bonds. Non-polar covalent bonds are incredibly rare, and only formed when there is a minute difference in the electronegativity of two atoms. Most commonly, they form between two atoms of the same type, which have no difference in electronegativity.
