They may be made of a weak acid and its conjugate base.
Substances with this property are secreted into the blood to rectify abnormalities detected in the CSF by the central chemoreceptors. Histidine residues on hemoglobin also perform this function in the blood via their imidazole sidechains. Tris is a component of these substances often used in electrophoresis. Intracellularly, H2PO4- and HPO42- ions are the primary substances with this function. The bicarbonate system in the blood is an example of one of these, whose range of effectiveness can be calculated with the Henderson-Hasselbalch equation. They may be made of a weak acid and its conjugate base. For 10 points, name these substances which resist changes in pH.
