1 Applesauce: Often used to replace oil in recipes, applesauce can also be used as a butter alternative, and it works best in cake-like recipes (like this vegan banana apple chunk bread).
a solution of ethanoic acid and sodium ethanoate .... One example is the blood. It's buffered mainly by H2CO3 (carbonic acid) and HCO3- (bicarbonate), both of which are produced through metabolic RXNs and ion exchanges from cells in the kidney tubules, even by the red blood cells themselves.t's buffered mainly by H2CO3 (carbonic acid) and HCO3- (bicarbonate), both of which are produced through metabolic RXNs and ion exchanges from cells in the kidney tubules, even by the red blood cells themselves.
Acid-base buffers confer resistance to a change in the pH of a solution when hydrogen ions (protons) or hydroxide ions are added or removed. An acid-base buffer typically consists of a weak acid, and its conjugate base (salt) (see Equations 2-4 in the blue box, below).he pK for the phosphate buffer is 6.8, which allows this buffer to function within its optimal buffering range at physiological pH. The phosphate buffer only plays a minor role in the blood, however, because H 3 PO 4 and H 2 PO 4 - are found in very low concentration in the blood.
