Crenarchaeol

Journal of Lipid Research, 2002
The basic structure and stereochemistry of the characteristic glycerol dibiphytanyl glycerol tetraether (GDGT) membrane lipid of cosmopolitan pelagic crenarchaeota has been identified by high field two-dimensional (2D)-NMR techniques.

Benthic archaea as potential sources of tetraether membrane lipids in sediments across an oxygen minimum zone [PDF]

Biogeosciences, 2018
Benthic archaea comprise a significant part of the total prokaryotic biomass in marine sediments. Recent genomic surveys suggest they are largely involved in anaerobic processing of organic matter, but the distribution and abundance of these archaeal ...

Archaeosomes and Tetraether Lipid Liposome

Pharmaceutical Sciences and Research, 2012
Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae- ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up the majority of total membrane lipids.

Energy flux controls tetraether lipid cyclization in Sulfolobus acidocaldarius [PDF]

Environmental Microbiology, 2019
Summary Microorganisms regulate the composition of their membranes in response to environmental cues. Many Archaea maintain the fluidity and permeability of their membranes by adjusting the number of cyclic moieties within the cores of their glycerol dibiphytanyl glycerol tetraether (GDGT) lipids.

Thermoplasmatales and Methanogens: Potential Association with the Crenarchaeol Production in Chinese Soils

Frontiers in Microbiology, 2017
Crenarchaeol is a unique isoprenoid glycerol dibiphytanyl glycerol tetraether (iGDGT) lipid, which is only identified in cultures of ammonia-oxidizing Thaumarchaeota. However, the taxonomic origins of crenarchaeol have been debated recently. The archaeal

Source, transport and fate of soil organic matter inferred from microbial biomarker lipids on the East Siberian Arctic Shelf [PDF]

Biogeosciences, 2016
The Siberian Arctic contains a globally significant pool of organic carbon (OC) vulnerable to enhanced warming and subsequent release by both fluvial and coastal erosion processes.

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Biosynthesis of archaeal membrane ether lipids

Frontiers in Microbiology, 2014
A vital function of the cell membrane in all living organism is to maintain the membrane permeability barrier and fluidity. The composition of the phospholipid bilayer is distinct in archaea when compared to bacteria and eukarya.

Subsurface Production of Marine Derived Bacterial Tetraether Lipids: Implications for Paleoceanographic Reconstruction

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are widely used as paleoclimate proxies on land, yet their origin in marine environments remains incompletely constrained. Here, we analyze suspended particulate matter collected from five depths at an open‐ocean station in the northern South China Sea and provide depth‐resolved evidence
