dolichols

A group of prenol derivatives in which $Math - text$ in the general formula H–[CH₂–C(CH₃)=CH–CH₂]_n–OH is greater than 4 and in which the residue that carries the hydroxy group is saturated, i.e. 2,3-dihydropolyprenols.

Note:

The collective term prenol should not be used without qualification to include dolichols since these are derivatives of prenols.
