Organic acid presence of other substituents that affect the polarity of the compound. Simple organic acids like formic or acetic acids are used for oil and gas well stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact times between acid and pipe are needed. The conjugate bases of organic acids such as citrate and lactate are often used in biologically-compatible buffer solutions. Citric and oxalic acids are used as
Beta-Hydroxybutyric acid Beta-Hydroxybutyric acid β-Hydroxybutyric acid, also known as (R)-3-hydroxybutyric acid, is an organic compound and a beta hydroxy acid with the chemical formula CHCH(OH)CHCOH; its conjugate base is β-hydroxybutyrate, also known as 3-hydroxybutyrate. β-Hydroxybutyric acid is a chiral compound with two enantiomers: -β-hydroxybutyric acid and -β-hydroxybutyric acid. Its oxidized and polymeric derivatives occur widely in nature. In humans, -β-hydroxybutyric acid is one of two primary endogenous agonists of hydroxycarboxylic acid receptor 2 (HCA), a G protein-coupled receptor (GPCR). In humans, can be synthesized in the liver via the metabolism of fatty acids (e.g., butyrate), , and ketogenic amino acids through a
