How about you and i go back to my place and do some math.

Like heme b, heme a is not covalently bound to the apoprotein it is found in.

Like heme b, heme a is not covalently bound to the apoprotein in which it is found.

polyglycylation, covalent linkage of one to more than 40 glycine residues to the tubulin C-terminal tail

The repulsion of lone pair electrons affects charge distribution and contributes to the polarity of a covalent bond.

The water molecules are thus subjected to a continuously charged field until the breakdown of the covalent bond occurs.

The electrons formerly shared by atoms in the water covalent bond are reallocated such that neutral elemental gases are liberated.

Heme c differs from heme b in that the two vinyl side chains are covalently bound to the protein itself.

Because an electron will only occupy a certain electron shell (shells are well known) the voltage applied to the capacitor affects the electrical forces inherent in the covalent bond.

A hemoprotein, or heme protein, is a protein containing a heme prosthetic group, either covalently or noncovalently bound to the protein itself. ...

Random covalent bonding of the nucleation points of these scale forming molecular clusters is reduced and, therefore, these minerals stay in suspension.

A hemeprotein (or hemoprotein or haemoprotein), or heme protein, is a metalloprotein containing a heme prosthetic group, either covalently or noncovalently bound to the protein itself.

Because an electron will only occupy a certain electron shell (the shells are well known) the voltage applied to the capacitor affects the electrical forces inherent in the co-valent bond.

Definition: A hemoprotein (or haemoprotein), or heme protein, is a metalloprotein containing a heme prosthetic group, either covalently or noncovalently bound to the protein itself.
