On the contrary, [HCO.sub.3]- binds a proton if blood pH is too acidic, resulting in H2CO3 again dissociating into water ([H.sub.2]O) and carbon dioxide ([CO.sub.2]).
This H2CO3 again dissociates into CO2 and H2O again in lungs where the concentration of CO2 is low [25].
When CO2 dissolves in water, it is partially converted into carbonic acid H2CO3, which may lower the pH of meat and bring it closer to the isoelectric point of proteins.
