Metabolite Identification
Common NameAcetoacetic acid
DescriptionAcetoacetic acid, also known as 3-oxobutyrate or 3-oxobutanoic acid, belongs to the class of organic compounds known as short-chain keto acids and derivatives. These are keto acids with an alkyl chain the contains less than 6 carbon atoms. Acetoacetic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Acetoacetic acid exists in all living species, ranging from bacteria to humans. Acetoacetic acid is a potentially toxic compound. Acetoacetic acid has been found to be associated with several diseases known as ketoacidosis, irritable bowel syndrome, anoxia, and diabetes mellitus type 2; also acetoacetic acid has been linked to the inborn metabolic disorders including glucose transporter type 1 deficiency syndrome.

General function:
Energy production and conversion
Specific function:
Catalyzes the cofactor-independent reversible oxidation of gamma-hydroxybutyrate (GHB) to succinic semialdehyde (SSA) coupled to reduction of 2-ketoglutarate (2-KG) to D-2-hydroxyglutarate (D-2-HG). L-3-hydroxybutyrate (L-3-OHB) is also a substrate for HOT when using 2-KG as hydrogen acceptor, resulting in the formation of D-2-HG (By similarity).

Specific function:
Dehydrogenase that mediates the formation of 2,5-dihydroxybenzoic acid (2,5-DHBA), a siderophore that shares structural similarities with bacterial enterobactin and associates with LCN2, thereby playing a key role in iron assimilation and homeostasis. Plays a role in susceptibility to bacterial infection by providing an assimilable source of iron that is exploited by pathogenic bacteria (By similarity). Also acts as a 3-hydroxybutyrate dehydrogenase (By similarity).

General function:
Amino acid transport and metabolism
Specific function:
Mitochondrial 3-hydroxymethyl-3-methylglutaryl-CoA lyase that catalyzes a cation-dependent cleavage of (S)-3-hydroxy-3-methylglutaryl-CoA into acetyl-CoA and acetoacetate, a key step in ketogenesis. Terminal step in leucine catabolism. Ketone bodies (beta-hydroxybutyrate, acetoacetate and acetone) are essential as an alternative source of energy to glucose, as lipid precursors and as regulators of metabolism.
