3,4-dihydroxybutyrate (BioDeep_00000021297)

描述信息

3,4-Dihydroxybutyric acid (also known as 3,4-Dihydroxybutanoic acid or 3,4-DB, or 2-deoxytetronic acid, or 2-DTA) is a normal human urinary metabolite that is excreted in increased concentration in patients with succinic semialdehyde dehydrogenase (SSADH) deficiency (PMID 12127325), which is a genetic disorder. SSADH deficiency is caused by an enzyme deficiency in GABA degradation. The most constant features with this disease are developmental delay, hypotonia and intellectual disability. Nearly half of SSADH patients exhibit ataxia, behavioral problems, seizures, and hyporeflexia. Normal adults excrete 0.37 +/- 0.15 (SD) mmoles of 3,4-dihydroxybutyrate per 24 hr. 3,4-dihydroxybutyrate is also detectable in blood. The renal clearance of 3,4-dihydroxybutyrate is roughly equal that of creatinine. 3,4-dihydroxybutyric acid has also been found in foods and is believed to be formed via the degradation (cooking) of di- and poly-saccharides (PMID: 1167165). 3,4-Dihydroxybutyric acid is believed to play a role in satiety or the feeling of fullness and suppresses food intake (PMID: 3191387; PMID: 6720928). 3,4-dihydroxybutyric acid is also elevated in the serum of individuals with dementia and may even serve as a predictive biomarker for dementia (PMID: 25177334). 3,4-Dihydroxybutyric acid is also a metabolite produced in Escherichia (PMID: 28342964).
