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.
The pH (or the amount of hydrogen ions (H+) in a solution) level of the blood is important in ensuring the proper functionality of biological systems. The optimal pH level of the blood is 7.4, which is maintained by three different types of buffer systems working in the body. The addition of an acid or a base to a substance changes its pH level. A buffer is a solution (or a substance) that has the ability to maintain pH and bring it back to its optimal value.
