Forms
The eight forms of vitamin E are divided into two groups; four are tocopherols and four are tocotrienols. They are identified by prefixes alpha-, beta-, gamma-, and delta-. Natural tocopherols occur in the RRR-configuration only. The synthetic form contains eight different stereoisomers and is called all-rac-α-tocopherol.

“Two forms move among the dead, high sleep
Who by his highness quiets them, high peace
Upon whose shoulders even the heavens rest,
Two brothers. And a third form, she that says
Good-by in the darkness, speaking quietly there,
To those that cannot say good-by themselves.”
—Wallace Stevens (1879–1955)
“A monarchy is the most expensive of all forms of government, the regal state requiring a costly parade, and he who depends on his own power to rule, must strengthen that power by bribing the active and enterprising whom he cannot intimidate.”
