Evidence suggests that strong ions can exist reversibly bound to proteins in a pH-dependent manner and that they can be recruited into the biological solution, modulating its strong ion difference in a process that opposes the acid base disturbances imposed on the system. These recruitable strong ions represent the solution’s “strong ions”. The physiological role of these protein-bound strong ion reserve in the buffering of acid base disorders is discussed.
