Carnosine has a pK a value of 6.83, making it a good buffer for the pH range of animal muscles. [8] Since beta-alanine is not incorporated into proteins, carnosine can be stored at relatively high concentrations (millimolar).
McIlvaine buffer is a buffer solution composed of citric acid and disodium hydrogen phosphate, also known as citrate-phosphate buffer.It was introduced in 1921 by the United States agronomist Theodore Clinton McIlvaine (1875–1959) from West Virginia University, and it can be prepared in pH 2.2 to 8 by mixing two stock solutions.
It is an effective buffer between the pH 5.8 and 7.2. Bis-tris methane binds strongly to Cu and Pb ions as well as, weakly, to Mg, Ca, Mn, Co, Ni, Zn and Cd. Bis-tris methane binds strongly to Cu and Pb ions as well as, weakly, to Mg, Ca, Mn, Co, Ni, Zn and Cd.
Good's buffers (also Good buffers) are twenty buffering agents for biochemical and biological research selected and described by Norman Good and colleagues during 1966–1980. [ 1 ] [ 2 ] [ 3 ] Most of the buffers were new zwitterionic compounds prepared and tested by Good and coworkers for the first time, though some ( MES , ADA , BES , Bicine ...

Tris-buffered saline (TBS) is a buffer used in some biochemical techniques to maintain the pH within a relatively narrow range. Tris (with HCl) has a slightly alkaline buffering capacity in the 7–9.2 range. The conjugate acid of Tris has a pK a of 8.07 at 25 °C. The pK a declines approximately 0.03 units per degree Celsius rise in ...
Berberine supplements, on the other hand, activate AMPK enzymes in your body, which work to regulate metabolism (offering potential benefits for weight loss), says Lee.
Universal buffers consist of mixtures of acids of diminishing strength (increasing pK a), so that the change in pH is approximately proportional to the amount of alkali added. It consists of a mixture of 0.04 M boric acid, 0.04 M phosphoric acid and 0.04 M acetic acid that has been titrated to the desired pH with 0.2 M sodium hydroxide. Britton ...
