Salicylates

2-Hydroxybenzoic acid ion(1-)

C7H5O3 (137.023868)


Salicylates, also known as 2-hydroxybenzoic acid or sal, is a member of the class of compounds known as salicylic acids. Salicylic acids are ortho-hydroxylated benzoic acids. Salicylates is soluble (in water) and a moderately acidic compound (based on its pKa). Salicylates can be found in a number of food items such as arabica coffee, apple, common thyme, and rosemary, which makes salicylates a potential biomarker for the consumption of these food products. Salicylic acid (from Latin salix, willow tree) is a lipophilic monohydroxybenzoic acid, a type of phenolic acid, and a beta hydroxy acid (BHA). It has the formula C7H6O3. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. In addition to serving as an important active metabolite of aspirin (acetylsalicylic acid), which acts in part as a prodrug to salicylic acid, it is probably best known for its use as a key ingredient in topical anti-acne products. The salts and esters of salicylic acid are known as salicylates .

   

4-hydroxybenzoate

4-Hydroxybenzoic acid, ion(1-)

C7H5O3 (137.023868)


4-hydroxybenzoate, also known as 4-hydroxybenzoic acid, dilithium salt or para-hydroxybenzoic acid, is a member of the class of compounds known as benzoic acids. Benzoic acids are organic Compounds containing a benzene ring which bears at least one carboxyl group. 4-hydroxybenzoate is soluble (in water) and a weakly acidic compound (based on its pKa). 4-hydroxybenzoate can be found in a number of food items such as fennel, silver linden, cucurbita (gourd), and chinese cabbage, which makes 4-hydroxybenzoate a potential biomarker for the consumption of these food products.
