«The net effect of this is that, although the total electronic charge on the molecule balances the total nuclear charge, each oxygen atom carries a
small net negative charge, and a balancing positive charge is associated with the carbon atom.
Since the skin has
a net negative charge under normal physiological conditions, interstitial fluid flows from within the skin towards a cathode on the skin surface, where glucose is then detected and analysed.
Anion An anion from the Greek word???, meaning «up», is an ion with more electrons than protons, giving
it a net negative charge (since electrons are negatively charged and protons are positively charged)» The opposite is a cation.
