The E/Z isomerization step in the biosynthesis of Z coniferyl alcohol in Fagus grandifolia Ehrh.
… (E) stereoisomeric form. However, in beech bark (Fagus grandifolia Ehrh.) only the corresponding cis (Z) monomers were found. Experiments with beech bark and 2-¹⁴C-labelled E ferulic acid, E coniferaldehyde, and E coniferyl alcohol revealed that these compounds were efficiently incorporated into …
