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.

Famous quotes containing the word forms:
“Our character is not so much the product of race and heredity as of those circumstances by which nature forms our habits, by which we are nurtured and live.”
—Marcus Tullius Cicero (106–43 B.C.)
“That food has always been, and will continue to be, the basis for one of our greater snobbisms does not explain the fact that the attitude toward the food choice of others is becoming more and more heatedly exclusive until it may well turn into one of those forms of bigotry against which gallant little committees are constantly planning campaigns in the cause of justice and decency.”
—Cornelia Otis Skinner (1901–1979)
“Media mystifications should not obfuscate a simple, perceivable fact; Black teenage girls do not create poverty by having babies. Quite the contrary, they have babies at such a young age precisely because they are poor—because they do not have the opportunity to acquire an education, because meaningful, well-paying jobs and creative forms of recreation are not accessible to them ... because safe, effective forms of contraception are not available to them.”
—Angela Davis (b. 1944)
