n.d., metabolite not detected.
Lipids were extracted from thylakoid samples before and after sonication, which included both thylakoids and attached PGs or thylakoids from which most PGs were removed. PG are isolated PGs.
Oxidized and reduced forms.
Unknown compounds were tentatively assigned to a compound class based upon their absorption spectrum.
The molecular mass of quinone 1 was determined by MS to be 746.6 D.
Cis- and trans-forms.
Other prenyl-lipids include chlorophyll a and b, two unknown tocopherol compounds, eight unknown carotenoid compounds, and seven unknown quinone compounds, which were assigned to a compound class based on their absorption spectrum.
