Bacteria present in soil and peat bog environments were previously found to produce
branched glycerol dialkyl glycerol tetraether membrane lipids (GDGTs) that are used as a …

Glycerol dialkyl glycerol tetraethers (GDGTs) are membrane-spanning lipids from Bacteria
and Archaea that are ubiquitous in a range of natural archives and especially abundant in …

Branched glycerol dialkyl glycerol tetraethers (GDGTs) are complex lipids of high molecular
