β-Hydroxybutyric acid, also known as 3-hydroxybutyric acid or BHB, is an organic compound and a beta hydroxy acid with the chemical formula CH 3 CH(OH)CH 2 CO 2 H; its conjugate base is β-hydroxybutyrate, also known as 3-hydroxybutyrate. β-Hydroxybutyric acid is a chiral compound with two enantiomers: D-β-hydroxybutyric acid and L-β-hydroxybutyric acid.
Hydroxybutyric acid is a group of four-carbon organic compounds that have both hydroxyl and carboxylic acid functional groups. [1] They can be viewed as derivatives of butyric acid . The carboxylate anion and the esters of hydroxybutyric acids are known as hydroxybutyrates . β-hydroxybutyric acid is relevant to human health as it is a member ...
Both acetoacetate and beta-hydroxybutyrate are acidic, and, if levels of these ketone bodies are too high, the pH of the blood drops, resulting in ketoacidosis. Ketoacidosis is known to occur in untreated type I diabetes (see diabetic ketoacidosis ) and in alcoholics after prolonged binge-drinking without intake of sufficient carbohydrates (see ...
[4] [3] Although, β-hydroxybutyrate is technically not a ketone due to the structure of the molecule (OH- attached to carbonyl group makes this an acid), β-HB acts like a ketone, providing the body with energy in the absence of glucose. [1] In fact, β-Hydroxybutyrate is the most abundant ketone-like molecule in the blood during ketosis. [5 ...
Ketone bodies are transported from the liver to other tissues, where acetoacetate and β-hydroxybutyrate can be reconverted to acetyl-CoA to produce reducing equivalents (NADH and FADH 2), via the citric acid cycle. Though it is the source of ketone bodies, the liver cannot use them for energy because it lacks the enzyme thiophorase (β ...
β-Hydroxybutyryl-CoA (or 3-hydroxybutyryl-coenzyme A) is an intermediate in the fermentation of butyric acid, and in the metabolism of lysine and tryptophan. [1] [2] The L-3-hydroxybutyl-CoA (or (S)-3-hydroxybutanoyl-CoA) enantiomer is also the second to last intermediate in beta oxidation of even-numbered, straight chain, and saturated fatty acids.

γ-Amino-β-hydroxybutyric acid (GABOB), also known as β-hydroxy-γ-aminobutyric acid (β-hydroxy-GABA), sold under the brand name Gamibetal among others, is an anticonvulsant which is used for the treatment of epilepsy in Europe, Japan, and Mexico.
