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.

—Fred Rogers (20th century)
“This is the Scroll of Thoth. Herein are set down the magic words by which Isis raised Osiris from the dead. Oh! Amon-Ra—Oh! God of Gods—Death is but the doorway to new life—We live today-we shall live again—In many forms shall we return-Oh, mighty one.”
—John L. Balderston (1899–1954)
