General description
This product is miscible with chloroform or ethanol. It is practically insoluble in water but it is miscible with ether, acetone, and vegetable oils. It is unstable to alkaline conditions.
α-Tocopherol is synthesized from γ-tocopherol by the action of enzyme γ-tocopherol methyltransferase. It is the major form of Vitamin E in human plasma. It is present in sunflower seed oil.
Application
(+)-α-Tocopherol has been used:
- as a food supplement for juvenile cobia fish
- to evaluate its protective effect on bisphenol A induced oxidative stress in rats
- to test its chemopreventive efficacy in estrogen-mediated mammary cancer rats
Biochem/physiol Actions
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.
α-Tocopherol is essential for the photosynthesis in Synechocystis sp. strain PCC 6803. Supplementation with α-Tocopherol decreases lipid peroxidation and platelet aggregation. It inhibits protein kinase C and may play key role in gene regulation.
Packaging
Packaged under argon in a sealed ampule.
Analysis Note
Approx. 670 mg D-α-tocopherol per gram. The non-α content is typically between 5-35 mg/g
Other Notes
Mixed constitutional (α, β, γ, δ) isomers.
Disclaimer
Subject to air oxidation.

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

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
