Chemical structure of caldarchaeol, a prototypical GDGT
Glycerol dialkyl glycerol tetraether lipids (GDGTs) are a class of membrane lipids synthesized by archaea and some bacteria, making them useful biomarkers for these organisms in the geological record. Their presence, structure, and relative abundances in natural materials can be useful as proxies for temperature, terrestrial organic matter input, and soil pH for past periods in Earth history.[1] Some structural forms of GDGT form the basis for the TEX86 paleothermometer.[1] Isoprenoid GDGTs, now known to be synthesized by many archaeal classes, were first discovered in extremophilic archaea cultures.[2] Branched GDGTs, likely synthesized by acidobacteriota,[3] were first discovered in a natural Dutch peat sample in 2000.[4]
