Novel glycerol dialkanol triols in sediments: transformation products of glycerol dibiphytanyl glycerol tetraether lipids or biosynthetic intermediates?

摘要

A glycerol dialkanol triol, similar in structure to glycerol dibiphytanyl glycerol tetraethers but devoid of the carbon atoms of one of the two glycerol termini, has been identified in Messinian sediments (～6 Ma) and characterised using quadrupole ion trap and Fourier transform-ion cyclotron resonance liquid chromatography-tandem mass spectrometry.
