Question

Quizplus · Accepted Answer

To convert the number of tocopherol equivalents to alpha-tocopherol, you should multiply by 0.8. This is because alpha-tocopherol has the highest biological activity among all forms of tocopherol, and is therefore used as a reference standard. One alpha-tocopherol equivalent (ATE) is defined as 1 mg of alpha-tocopherol. Other forms of tocopherol have lower biological activity, so they require a higher amount to provide the same level of vitamin E activity as alpha-tocopherol. For example, 1 mg of gamma-tocopherol provides only 0.6 ATE, so to convert gamma-tocopherol equivalents to alpha-tocopherol equivalents, you would multiply by 0.6.
