fixed acids

Fixed acids are acids produced by the body's metabolism that do not evaporate easily, unlike volatile acids such as carbon dioxide. They mainly come from the breakdown of dietary proteins, producing acids like sulfuric acid and phosphoric acid. The body maintains a balanced pH in the blood by neutralizing these acids with buffers and excreting them through the kidneys. Excess fixed acids can lead to a condition called metabolic acidosis, where the blood becomes too acidic, disrupting normal body functions. Proper kidney function and respiratory health are essential for managing fixed acid levels and maintaining acid-base balance.
