Word History

Etymology

toco- (combining form from Greek tókos "childbirth, act of giving birth [of animals]") + Greek phérein "to carry, bring, bring about, produce" + -ol entry 1; so named because it was found to be a dietary factor essential for reproduction in rats — more at dystocia, bear entry 2

Note: The name tocopherol was introduced in an article by the American anatomist and embryologist Herbert McLean Evans (1882-1971), the biochemist and nutritionist Gladys Anderson Emerson (1903-84), and the biochemist Oliver Huddleston Emerson ("The isolation from wheat germ oil of an alcohol, α-tocopherol, having the properties of Vitamin E," Journal of Biological Chemistry, vol. 113, no. 1 [February 1, 1936], pp. 319-32). The isolation of α-tocopherol is generally credited to Gladys Emerson.
