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:
“... it seems to have been my luck to stumble into various forms of progress, to which I have been of the smallest possible use; yet for whose sake I have suffered the discomfort attending all action in moral improvements, without the happiness of knowing that this was clearly quite worth while.”
—Elizabeth Stuart Phelps (1844–1911)
“A strange effect of marriage, such as the nineteenth century has made it! The boredom of married life inevitably destroys love, when love has preceded marriage. And yet, as a philosopher has observed, it speedily brings about, among people who are rich enough not to have to work, an intense boredom with all quiet forms of enjoyment. And it is only dried up hearts, among women, that it does not predispose to love.”
—Stendhal [Marie Henri Beyle] (1783–1842)
“Culture’s essential service to a religion is to destroy intellectual idolatry, the recurrent tendency in religion to replace the object of its worship with its present understanding and forms of approach to that object.”
—Northrop Frye (b. 1912)
