A protein is composed of amino acids, which are held together by the covalent bonds known as:
phosphodiester bonds
ester bonds
glycosidic bonds
ether bonds
peptide bonds
The most important atomic property for explaining bonding behavior is the
number of protons.
number of electrons in the valence energy level.
mass of the atom.
