Editing ChargeCalculator:Terminology (section)

== Molecular charge ==
The '''total molecular charge''' is a formal value based on the molecular structure and the protonation state of all ionizable groups. The process of atomic charge calculation in ACC consists of distributing the amount of electron density given by the '''total molecular charge''' across the molecule, to each atom based on certain criteria and algorithms. Thus, the sum of atomic charges over all atoms in a molecule equals the total molecular charge. Similarly, the sum of residue charges over all residues in a molecule equals the total molecular charge.
