Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions.

The name ficin was first used by Robbins in 1930 to describe a purified substance with anthelmintic activity isolated from any member of the fig genus. [6] The Enzyme Commission of the International Union of Biochemistry and Molecular Biology (IUBMB) originally assigned EC 3.4.4.12 as ficin in 1961, which was transferred to 3.4.22.3 and renamed to ficain in 1972, making the two term synonymous ...
