/ˈfʌɪtɪl/,

/ˈfʌɪtʌɪl/, U.S.

/ˈfaɪdl/

Origin: Formed within English, by derivation. Etymons: phytol n., -yl suffix.

Etymology: < phyt- (in phytol n.) + -yl suffix.

Chemistry.

The monovalent radical —OC₂₀H₃₉, derived from phytol by the loss of a hydrogen atom, and present as a constituent in various biologically important molecules including chlorophyll and vitamins E and K.
