Cassidy (1) fully outlines the historical progress of research to 1968 about the carbamate reaction; this paper will simply summarize that effort. It is presently believed that carbon dioxide is transported by the blood in three ways: 1) dissolved CO2 and carbonic acid, 2) bicarbonate ions, and 3) carbamate. Roughton and Rossi-Bernardi (10) have proposed the use of a glycylglycine and CO2 model for the carbamate reaction. Instead of the barium precipitate method, they have used a pH and pCO2 electrode system to measure the uptake of CO2. Since the dissolved CO2 and HCO3 can be calculated from the pCO2 and pH measurements using the Henderson-Hasselbalch equation, the original CO2 concentration only need be known to calculate the amount of carbamate formed.
