3-Hydroxysebacic acid (BioDeep_00000018441)

描述信息

3-Hydroxydecanedioic is a dicarboxylic acid that belongs to the class of compounds known hydroxy fatty acids. Hydroxy fatty acids are fatty acids that have hydroxyl functional groups attached to the principal chain. 3-Hydroxydecanedioic acid is found in most vertebrates. Urine from patients with ketoacidosis typically contains a number of aliphatic 3-hydroxy dicarboxylic acids, with the major compound being 3-hydroxydecanedioic acid (PMID: 7353273). The excretion of 3-hydroxydecanedioic acid is correlated with the excretion of hexanedioic acid, another metabolite frequently found in ketoacidosis (PMID: 5031780). It is thought that the 3-hydroxy dicarboxylic acids such as 3-hydroxydecanedioic acid are formed from fatty acids by a combination of omega-oxidation and incomplete beta-oxidation (PMID: 7353273). Marked elevation of urinary 3-hydroxydecanedioic acid has also been reported in a malnourished infant with glycogen storage disease (PMID: 8295400). Subsequent studies have shown that increased amounts of dicarboxylic acids, such as 3-hydroxydecanedioic acid, are typically excreted in human urine under conditions of medium-chain triglyceride (MCT) feeding, abnormal fatty acid oxidation (FAO) and fasting (PMID: 8596483).
3-Hydroxysebacic acid is a normal urinary 3-hydroxydicarboxylic acid metabolite and can be elevated in patients with peroxisomal disorders such as Zellweger syndrome. Marked elevation of urinary 3- Hydroxysebacic acid has also been described in a malnourished infant with glycogen storage disease, mimicking long-chain L-3-hydroxyacyl-CoA dehydrogenase deficiency (OMIM 300438, a defect in the beta-oxidation of fatty acids characterized by massive excretion of 3-hydroxydicarboxylic acids in the urine and accumulation of 3-hydroxy fatty acids in serum).
