Example sentences for: alpha-tocopherol

How can you use “alpha-tocopherol” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The increased cellular uptake of alpha-tocopherol caused by gamma-tocopherol could be caused by gamma-tocopherol protecting alpha-tocopherol from in vitro oxidation to its quinone form.

  • After 6 hr, macrophages incubated with both alpha- and gamma-tocopherol accumulated about 0.5 nmole more alpha-tocopherol than did macrophages incubated with alpha-tocopherol alone.

  • It is interesting, however, that in an animal model, graded levels of dietary gamma-tocopherol in a diet containing a constant level of alpha-tocopherol were found to increase the levels of alpha-tocopherol in serum and most tissues [ 16 ] . This remarkable result has yet to be reproduced in humans but certainly suggests an interaction between dietary gamma-tocopherol and alpha-tocopherol similar to that reported here on the cellular level.

  • Under in vitro conditions, alpha- and gamma-tocopherol have very similar abilities to inhibit lipid peroxidation in large unilamellar liposomes [ 5 ] . The dietary intake of gamma-tocopherol is at least two times that of alpha-tocopherol in Western diets.

  • Since gamma-tocopherol is depleted from macrophages more rapidly than alpha-tocopherol the time interval between removal of the tocopherol enriched medium and cell harvesting could be an important variable.
