The matrix of supragingival calculus constitutes 15.7% of the calculus dry weight and contains 54.9% protein and 10.2% lipids. Of the total lipids, 61.8% are represented by neutral lipids, 28% by glycolipids, and 10.2% by phospholipids.

Archaeol as a methanogen biomarker in ombrotrophic bogs

open access: yes, 2011
In order to develop new tools in the reconstruction of microbiological processes in ancient continental settings, we determined the concentration of archaeol and sn-2-hydroxyarchaeol in four Holocene ombrotrophic peatlands, spanning a range of European ...

Sulfated archaeol glycolipids: comparison with other immunological adjuvants in mice

open access: yes, 2018
Archaeosomes are liposomes traditionally comprised of total polar lipids (TPL) or semi-synthetic glycerolipids of ether-linked isoprenoid phytanyl cores with varied glyco- and amino-head groups.

Identification of CDP-Archaeol Synthase, a Missing Link of Ether Lipid Biosynthesis in Archaea

open access: yes, 2014
SummaryArchaeal membrane lipid composition is distinct from Bacteria and Eukarya, consisting of isoprenoid chains etherified to the glycerol carbons. Biosynthesis of these lipids is poorly understood.

Electrogenerated poly(pyrrole-lactosyl) and poly(pyrrole-3’-sialyllactosyl) interfaces: towards the impedimetric detection of lectins

open access: yes, 2013
This paper reports on the impedimetric transduction of binding reaction between polymerized saccharides and target lectins. The controlled potential electro-oxidation of pyrrole-lactosyl and pyrrole-3’-sialyllactosyl at 0.95 V vs Ag/AgCl, provides thin ...

Synthesis of S-hepta-O-acetyl lactosyl-1,5-disubstituted-2-isothiobiurets and 1,5-disubstituted-2,4-isodithiobiurets

open access: yes, 2006
1285-1287Several S-hepta-O-acetyl lactosyl-1,5-disubstituted-2-isothio­biurets 4 and 1,5-disubstituted-2,4-isodithiobiurets 5 have been synthesized by the interaction of S-hepta-O-acetyl lactosyl-1-arylisothiocarbamides 3 with phenyl isocyanate and ...

Structural and mechanistic insights into the biosynthesis of CDP-archaeol in membranes [PDF]

open access: yes, 2017
The divergence of archaea, bacteria and eukaryotes was a fundamental step in evolution. One marker of this event is a major difference in membrane lipid chemistry between these kingdoms.

open access: yes, 2016
Schematic representation of completely non-6-O-sulfated ([NSIS]6), site-selectively mono-6-O-sulfated ([NSIS6S]-[NSIS]5) and fully 6-O-sulfated ([NS6SIS]6) dodecasaccharides.
