[delta]^sup 15^N Enrichment Suggests Possible Source for Halogenated 1'-Methyl-1,2'-bipyrroles (MBPs)
Polyhalogenated 1'-methyl-1,2'-bipyrroles are natural products that biomagnify into upper trophic levels of marine food webs. Here we demonstrate that they are unusually enriched in ... (... from +19.3%... to +28.1%...) relative to other biosynthetic organic compounds measured to date and...
