Fluorosulfuric acid Fluorosulfuric acid Fluorosulfuric acid (IUPAC name: sulfurofluoridic acid) is the inorganic compound with the chemical formula HSOF. It is one of the strongest acids commercially available. The formula HSOF emphasizes its relationship to sulfuric acid, HSO; HSOF is a tetrahedral molecule. It is a colourless liquid, although commercial samples are often yellow. Fluorosulfuric acid is a free-flowing colorless liquid. It is soluble in polar organic solvents (e.g. nitrobenzene, acetic acid, and ethyl acetate), but poorly soluble in nonpolar solvents such as alkanes. Reflecting its strong acidity, it dissolves almost all organic compounds that are even weak proton acceptors. HSOF hydrolyzes
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
