Black lipid membranes of tetraether lipids from Thermoplasma acidophilum
Lipids and Lipid Metabolism, 1992Black lipid membranes were formed of tetraether lipids from Thermoplasma acidophilum and compared to the bilayer forming lipids diphytanoylphosphatidylcholine and diphythanylglucosylglycerol. Bilayer-forming lipids varied in thickness of black lipid membranes due to the organic solvent used. Measurements of the specific membrane capacitance (Cm = 0.744

Oral delivery of vancomycin by tetraether lipid liposomes
European Journal of Pharmaceutical Sciences, 2017 Despite the outstanding progress in modern medicine, the oral delivery of peptide drugs is limited until today due to their instability in the gastrointestinal tract and low mucosa penetration. To overcome these hurdles, liposomes containing the specific tetraether lipid GCTE (glycerylcaldityltetraether lipid) were examined.

Molecular modeling of archaebacterial bipolar tetraether lipid membranes
Chemistry and Physics of Lipids, 2000Membranes composed of glycerol dialkylnonitol tetraether (GDNT) lipids from the thermoacidophilic archaebacterium Sulfolobus acidocaldarius have been studied by molecular modeling. GDNT membranes containing eight cyclopentane rings in the molecule are packed much tighter than those without rings.

Archaeal Tetraether Lipids: Unique Structures and Applications
Applied Biochemistry and Biotechnology, 2002The extremely stable biomolecules manufactured by organisms from extreme environments are of great scientific and engineering interest in the development of robust and stable industrial biocatalysts. Identification of molecules that impart stability under extremes will also have a profound impact on our understanding of cellular survival.

Oral peptide delivery by tetraether lipid liposomes
International Journal of Pharmaceutics, 2011The aim of this study is to improve of oral peptide delivery by a novel type of liposomes containing tetraether lipids (TELs) derived from archaea bacteria. Liposomes were used for the oral delivery of the somatostatin analogue octreotide. TELs were extracted from Sulfolobus acidocaldarius and subsequently purified to single compounds.

Biradical Tetraether Lipids from Thermoacidophilic Archaebacteria
1988Archaebacteria are a novel class of micro-organisms, commonly encountered in exceptional ecological niches: methanogens in the absence of oxygen and in the presence of hydrogen and carbon dioxide, halophiles at high salt concentration, thermophiles at high temperature ranging from 60° to 105°. A variety of phylogenetic arguments has led some authors to

Purification and characterization of a liposomal-forming tetraether lipid fraction
Biochemical and Biophysical Research Communications, 1990Polar lipid E, PLE, a native tetraether lipid mixture from Sulfolobus acidocaldarius is shown to spontaneously form multilamellar liposomes in aqueous media. PLE lipids were isolated as a single fraction from the crude lipid extract of S. acidocaldarius on a reverse-phase column followed by TLC and methanol precipitation.

Archaeal tetraether bipolar lipids: Structures, functions and applications
Biochimie, 2009Archaea have developed specific tools permitting life under harsh conditions and archaeal lipids are one of these tools. This microreview describes the particular features of tetraether-type archaeal lipids and their potential applications in biotechnology.
