Formulation of dynamic buffer capacity for phytic acid

Abstract

The general formulation of dynamic buffer capacity for polyprotic acids and bases (and polyprotic acid and base salts) has been derived. Polyprotic acids show buffer capacity over a broad range of pH values, according to their successive protonation constants. Polyprotic acids with equidistant pki values behave as universal buffers. The paper covers the dynamic buffer capacity for phytic acid, which posse’s twelve acid groups. Phytic acid, the hexaphosphate ester of myoinositol, has a great biological relevance, and shows antioxidant/anticancer properties.
