Description

Application

Meso-Erythritol (i-Erythritol) is a precursor to the important tanning agent L-erythrulose which can be commercially generated by Gluconobacter oxydans DSM 7145. Meso-Erythritol may be used to support the carbon source growth requirement of Gluconobacter bacteria. It is an aliphatic poly-alcohol used in the chemical analysis of the reactivity of various radicals and radical anions. Meso-Erythritol may be used in encapsulated phase change materials (PCMs) to study its potential use in microelectronics cooling applications. It may be used as a reference compound in purification and analytical procedures developed to test fermentation broths.

Biochem/physiol Actions

Allelic variation of the Tas1r3 gene affects behavioral taste responses to this sugar alcohol, suggesting that it is a T1R3 receptor ligand.
