Salicylic acid is an organic compound with the formula HOC 6 H 4 COOH. [3] A colorless (or white), bitter-tasting solid, it is a precursor to and a metabolite of acetylsalicylic acid (aspirin). [3] It is a plant hormone, [8] and has been listed by the EPA Toxic Substances Control Act (TSCA) Chemical Substance Inventory as an experimental ...

pK a values of amino acid side chains play an important role in defining the pH-dependent characteristics of a protein. The pH-dependence of the activity displayed by enzymes and the pH-dependence of protein stability , for example, are properties that are determined by the p K a values of amino acid side chains.
[citation needed] This test was not specific to acetylsalicylic acid but would occur in the presence of any phenol or enol. The downfall of this test occurs in the presence of hyperbilirubinemia or elevated bilirubin. When the level of bilirubin exceeds 1 mg/dl, a false positive could occur. [citation needed]
The therapeutic effects of salicylic acids were first documented in 1763 by Edward Stone, with acetylsalicylic acid being synthesized by Felix Hoffmann, a chemist working under Bayer, in 1897. [4] Acetylsalicylic acid-derived salt compounds were first discovered in 1970, [5] and the synthesis of lysine acetylsalicylate was first documented in ...
In practice, the mixture can be created by dissolving the acid in water, and adding the requisite amount of strong acid or base. When the p K a and analytical concentration of the acid are known, the extent of dissociation and pH of a solution of a monoprotic acid can be easily calculated using an ICE table .
Salicin is found in the bark of and leaves of willows, poplars and various other plants. [5] Derivates are found in castoreum.Salicin from meadowsweet was used in the synthesis of aspirin (acetylsalicylic acid), [6] in 1899 by scientists at Bayer.
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
