Other Notes
Mixed isomers
包装
Packaged under argon in a sealed ampule.
Quality
Approx. 670 mg D-α-tocopherol per gram. The non-α content is typically between 5-35 mg/g
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.
Physical properties
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.
