Descripción general

α-Tocopherol is the active form of vitamin E.[1] It functions as an hydroperoxyl radical scavenger and protects the organism from oxidative damage. α-Tocopherol plays a crucial role in cell signalling and regulating immune responses.[2] α-Tocopherol deficiency is associated with abetalipoproteinemia, cystic fibrosis and celiac disease.[1] It has antiproliferative effects.[3] It inhibits arsenite-induced damage of human fibroblasts.[4]

Aplicación

α-Tocopherol has been used:
  • as a standard to determine its concentration by reverse-phase high-performance liquid chromatography[5][6]
  • to study its rescue effects on chlorine dioxide (ClO2) cytotoxicity[7]
  • to assess its protective effects on acetaminophen (APAP)-mediated liver damage[8]

Acciones bioquímicas o fisiológicas

Tocopherols (TCP) (vitamin E) are a series (α, β, γ and δ) of chiral organic molecules that vary in their degree of methylation of the phenol moiety of the chromanol ring. Tocopherols are lipid soluble anti-oxidants that protect cell membranes from oxidative damage. α-Tocopherol is the form of tocopherol preferentially absorbed by homo sapiens. Various isofroms and analogues of tocopherol have opposing and differentiated regulatory activities in vivo.

Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.

Questions

1–3 of 3 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.

  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

  3. Could you please provide the concentration of this product (mg/ml)?

    1 answer

    1. This product is a neat or pure liquid and has not been diluted. This material has a density of 0.950 g/mL and a molecular weight of 430.71 g/mol. The minimum purity is 95.5%, thus the molarity will vary slightly from lot to lot. The molarity can range from 2.11M (95.5%) to 2.20M (100%).
