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.

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

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

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
