Web“A buffer is an aqueous solution that resists changes in pH upon the addition of an acid or a base”. Also, adding water to a buffer or allowing water to evaporate from the buffer does not change the pH of a buffer significantly. WebThe last buffer system makes use of proteins in the blood plasma or fluid called albumins and certain proteins in the cells including the structure (i.e., the protein but not the heme itself) of the oxygen-carrier hemoglobin. A single protein molecule can function as either an acid or a base depending on the pH of its environment (Fig. 3).
