a
+++, most abundant in base peak chromatogram (BPC); ++, 50 to 100%; +, 10 to 50%; tr, trace. Note that the ionization efficiency under the LC/MS conditions of different IPLs may vary substantially, which indicates that peak heights in BPCs are not necessarily a reflection of their abundance.
b
Possibly a glucuronic acid head group.
c
This IPL contains a hydroxy-GDGT core instead of a more common GDGT core.
