protein buffer
Three common buffer systems are the bicarbonate buffer system in blood, the phosphate buffer system in intracellular fluid, and the protein buffer system in plasma. These systems help maintain a stable pH in the body by absorbing or releasing hydrogen ions as needed.
The bicarbonate buffer system is the most abundant buffer system in the body. It helps regulate pH in the blood by maintaining a balance between carbonic acid (H2CO3) and bicarbonate ions (HCO3-).
The major intracellular buffer is the bicarbonate-carbonic acid system. Its equilibrium helps to maintain the pH balance within cells by accepting or donating protons (H+) to prevent excessive changes in acidity or alkalinity. This buffer system is vital for regulating cellular functions and maintaining homeostasis.
The bicarbonate buffer system is the most important buffer in extracellular fluids, including blood. It helps maintain the pH level of the body within a narrow range by regulating the levels of bicarbonate ions and carbonic acid.

Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3
The buffer system in whole blood is made up of carbonic acid-bicarbonate buffer system and protein buffer system. The carbonic acid-bicarbonate buffer system helps regulate pH by balancing the levels of carbonic acid and bicarbonate ions. The protein buffer system involves proteins like hemoglobin that can bind to and release hydrogen ions to help maintain a stable pH in the blood.
Buffer systems help to maintain constant plasma pH. There are three buffer systems - Protein buffer system, phoshate buffer system and bicarbonate buffer system. Among this, bicarbonate buffer system is the most predominant. Buffers function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3
The buffer system in blood is formed by carbonic acid (H2CO3) and bicarbonate ions (HCO3-). This system helps maintain the pH of blood within a narrow range by absorbing or releasing hydrogen ions as needed.
Carbonic acid-bicarbonate buffer system Acids (H+) released into the blood by the body cells tend to lower the pH of the blood and cause it to be acidic. Alkali resists a rise in pH
The major plasma buffering system in the body consists of bicarbonate (HCO3-) and carbonic acid (H2CO3). This system helps maintain the pH balance in the blood by shifting between bicarbonate and carbonic acid in response to changes in hydrogen ion concentration.
