Environmental and biochemical controls on the molecular distribution and stable isotope composition of leaf wax biomarkers
… chloroplast-synthesised compounds (fatty acids, phytol) suggested these differences instead reflected the varied biochemical mechanisms operating in the chloroplast and cytosol. Sedimentary biomarker analysis further highlighted that small/moderate vegetation change could drive shifts of ~40‰ in …
