Applicazioni

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.[1] 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.[2]

Azioni biochim/fisiol

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

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

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

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
