Abstract: pH of blood and intracellular compartments is tightly regulated. Blood pH at 37 ยฐC is 7.4. However, when temperature is lowered, the pH of blood and of intracellular buffer systems increases, which has been reported as early as 1927 but was ignored for the following 30 years. The phenomenon of a change in blood pH with temperature of about -0.016 U/ยฐC was rediscovered by comparative physiologists in studies of "cold blooded" vertebrates (turtles, fish), and is was recognized soon that the same pH/temperature relation applies to "warm blooded" mammals (rat, human). The physicochemical basis of pH/temperature relations and the consequences for acid-base balance and protein function were primarily analyzed by Rahn and Reeves (1979). Besides the importance for physiological and biochemical systems, the temperature dependence of pH of buffer systems has experimental significance for the measurement of pH at different temperatures, and for the choice of buffer systems when designing experiments at various temperatures.
