WebProtein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. The protein hemoglobin makes an excellent buffer. It can bind to small amounts of acid in the blood, helping to remove that acid before it changes the blood's pH. Many other proteins act as buffers as well.

WebDec 13, 2024 · The protein hemoglobin makes an excellent buffer. It can bind to small amounts of acid in the blood, helping to remove that acid before it changes the blood’s pH. How is the pH of a buffer system maintained? The buffer systems in and outside cells help maintain that pH. In chemistry and biochemistry, the acidity of a solution is called pH. WebWhile the third buffer is the most plentiful, the first is usually considered the most important since it is coupled to the respiratory system. Carbonic acid (H 2 CO 3) is a weak acid and is therefore in equilibrium with bicarbonate (HCO 3-) in solution. When significant amounts of both carbonic acid and bicarbonate are present, a buffer is formed.
