acetoacetate
Acetoacetate, also known as acetoacetic acid or oxobutyrate, belongs to short-chain keto acids and derivatives class of compounds. Those are keto acids with an alkyl chain the contains less than 6 carbon atoms. Acetoacetate is soluble (in water) and a weakly acidic compound (based on its pKa). Acetoacetate can be found in a number of food items such as plains prickly pear, daikon radish, papaya, and common chokecherry, which makes acetoacetate a potential biomarker for the consumption of these food products. Acetoacetic acid (also diacetic acid) is the organic compound with the formula CH3COCH2COOH. It is the simplest beta-keto acid group, and like other members of this class, it is unstable. The methyl and ethyl esters, which are quite stable, are produced on a large scale industrially as precursors to dyes. Acetoacetic acid is a weak acid .
Butyrate
A short-chain fatty acid anion that is the conjugate base of butyric acid, obtained by deprotonation of the carboxy group.
