Origin: A borrowing from German. Etymon: German Prenyl.

Etymology: < German Prenyl (E. Späth & J. Bruck 1938, in Berichte der Deutsch. Chem. Ges. 71 2708) < pren- (in Prenol prenol n.) + -yl -yl suffix.

Chemistry.

A hydrocarbon radical or group C₅H₈, present in prenols and in polymers of isoprene; an isoprene residue. Usually attributive.

1939 Chem. Abstr. 33 col. 1687 The name prenol is suggested for the primary alc. contg. residue I, viz., Me₂C:CHCH₂OH,..and prenyl for the residue itself.

1962 Tetrahedron Lett. No. 1. 12 Isoartocarpin is also unique as the only natural flavone so far isolated which contains a prenyl (3,3-dimethylallyl) ether group.

1976 Nature 17 June 621/2 The new form..turned out to be one member of a large family of menaquinones denoted MK-n, where n is the number of prenyl (C₅H₈) groups in the polyprenyl sidechain.

2004 Chem. & Industry (Nexis) 6 Sept. 16 The plant makes genistein and then decorates it with prenyl groups as a defence strategy.
