Archaeal lipids record paleosalinity in hypersaline systems

Organic Geochemistry, 2011
Abstract We present an ecologically based biomarker method for estimating past salinity, especially in hypersaline conditions. The relative amounts of acyclic diether and tetraether membrane lipids synthesized by Archaea correlate with salinity from 0–250 practical salinity units (psu) in modern settings.

Archaeal lipids in Neogene dolomites (Monterey and Sisquoc Formations, California) – Planktic versus benthic archaeal sources

Organic Geochemistry, 2011
Abstract The distribution of archaeal lipids, including archaeol and glycerol dibiphytanyl glycerol tetraethers (GDGTs), in dolomite concretions and surrounding sediment from the Monterey Formation (Miocene) and the Sisquoc Formation (Miocene–Pliocene) were examined to distinguish planktic from benthic contributions.

Dynamics and Organization of Archaeal Tetraether Lipid Membranes

2017
Archaeal bipolar tetraether lipids (BTLs) have distinct structural differences from the lipids isolated from bacteria and eukaryotes. Because of the presence of the unusual structural features, such as macrocyclic structures, cyclopentane rings, isoprenoid units, tetraether linkages, and a variety of polar head groups, archaeal BTL membranes possess ...

Archaeal Lipids as an Adaptation to Higher Temperatures?

2017
A hypothesis is presented that the lipids of Archaea are an adaptation to a high temperature origin, possibly as an adaptation to higher sea temperatures during an early bombardment? This is separate from the issue that Eukaryotes arose before Prokaryotes (Akaryotes on our terminology). Archaeal lipids are basically isoprenoid compounds.

Archaeal lipids: structural features and supramolecular organization

Thin Solid Films, 1996
Abstract The Archaea domain, formed exclusively of extremophilic prokaryotic organisms, represents a third evolutive line distinct from the wellknown Eubacteria and Eukarya domains. Archaeal lipids are based on ether links and their aliphatic components are isoprenic in nature.
