Threonic acid

2,3,4-Trihydroxy-(threo)-butanoic acid

C4H8O5 (136.0372)


Threonic acid, also known as threonate, belongs to the class of organic compounds known as sugar acids and derivatives. Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. Threonic acid is a sugar acid derived from threose. The L-isomer is a metabolite of ascorbic acid (vitamin C). One study suggested that because L-threonate inhibits DKK1 expression in vitro, it may have potential in the treatment of androgenic alopecia (PMID:21034532). Threonic acid is probably derived from glycated proteins or from degradation of ascorbic acid. It is a normal component in aqueous humour and blood (PMID:10420182). Threonic acid is a substrate of L-threonate 3-dehydrogenase (EC 1.1.1.129) in the ascorbate and aldarate metabolism pathway (KEGG). It has been found to be a microbial metabolite (PMID:20615997). L-threonic acid, also known as L-threonate or L-threonic acid magnesium salt, belongs to sugar acids and derivatives class of compounds. Those are compounds containing a saccharide unit which bears a carboxylic acid group. L-threonic acid is soluble (in water) and a weakly acidic compound (based on its pKa). L-threonic acid can be found in a number of food items such as buffalo currant, yam, purslane, and bayberry, which makes L-threonic acid a potential biomarker for the consumption of these food products. L-threonic acid can be found primarily in blood. Threonic acid is a sugar acid derived from threose. The L-isomer is a metabolite of ascorbic acid (vitamin C). One study suggested that because L-threonate inhibits DKK1 expression in vitro, it may have potential in treatment of androgenic alopecia .

Erythronic acid

(R*,r*)-2,3,4-trihydroxy-butanoic acid

C4H8O5 (136.0372)


Erythronic acid is a sugar component of aqueous humour (eye). It may be derived from glycated proteins or from degradation of ascorbic acid. Erythronic acid is a normal organic acid present in a healthy adult and pediatric population. It has been found in urine, plasma, CSF, and synovial fluid (PMID: 14708889, 8087979, 8376520, 10420182). Erythronic acid is formed when N-acetyl-D-glucosamine (GlcNAc) is oxidized. GlcNAc is a constituent of hyaluronic acid (HA), a polysaccharide consisting of alternating units of glucuronic acid and GlcNAc, present as an aqueous solution in synovial fluid. In the synovial fluid of patients suffering from rheumatoid arthritis, HA is thought to be degraded either by radicals generated by Fenton chemistry (Fe2+/H2O2) or by NaOCl generated by myeloperoxidase (PMID: 10614067). Erythronic acid is a sugar component of aqueous humour (eye). It may be derived from glycated proteins or from degradation of ascorbic acid. Erythronic acid is a normal organic acid present in a healthy adult and pediatric population. It has been found in urine, plasma, CSF and synovial fluid.
