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.

Actions biochimiques/physiologiques

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

Previous studies have demonstrated various combinations of non-nutritive erythritol and sucrose having detrimental effects on Drosophila suzukii (Matsumura). Fly mortality is likely caused by 1) starvation from feeding on non-metabolizable erythritol; and 2) physiological imbalance with abnormally high osmotic pressure

Keratinocytes were dissociated from normal human adult epidermis with clostridial collagenase, dithio-erythritol and trypsin, and cultured. Immediately after this, no connection was seen between contiguous cells. Ruptured desmosomes, with masses of tonofilaments and distinct attachment plaques were still left on

Plastid-derived signals are known to coordinate expression of nuclear genes encoding plastid-localized proteins in a process termed retrograde signaling. To date, the identity of retrograde-signaling molecules has remained elusive. Here, we show that methylerythritol cyclodiphosphate (MEcPP), a precursor of isoprenoids
