Application of stable and radioisotope precursor/tracer experiments resulted in the
identification of various phenylpropanoid, monolignol, and lignan metabolites involved in the
biosynthesis of the cancer chemopreventive secoisolariciresinol diglucoside (SDG; 1)-
containing ester-linked “polymer (s)” in flax (Linum usitatissimum) seed. Individual analysis
of size-segregated flax seed capsules at five early stages of their development provided a
metabolic profile of intermediates leading to “biopolymer” biosynthesis. The use of 1H and …
