The chain length of lignan macromolecule from flaxseed hulls is determined by the incorporation of coumaric acid glucosides and ferulic acid glucosides

An inverse relationship between the amount of CouAG + FeAG and the molecular mass of lignan macromolecule from flaxseed hulls was found, suggesting that lignan macromolecule is terminated by CouAG and/or FeAG. It is hypothesized that the amount of CouAG + FeAG present during biosynthesis determines the chain length.
