The cell membrane of archaea consist mostly of ether phospholipids. These lipids have a flipped chirality compared to bacterial and eukaryotic membranes, a conundrum known as the " lipid divide ". The "tail" groups are also not simply n-alkyl groups, but highly methylated chains made up of saturated isoprenoid units (e.g. phytanyl ).
This resulted in the breakage of the plasmalogen vinyl-ether bond to yield aldehydes. In turn, the latter reacted with a fuchsine-sulfurous acid stain used in this nuclear staining method and gave rise to colored compounds inside the cytoplasm of the cells. Plasmalogens were named based on the fact that these colored compounds were present in ...
Phospholipids [1] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. [2]
Phospholipids are the primary lipids composing cellular membranes. Phospholipids can be saponified, which releases the fatty acids contained in their diglyceride tail. Once the phospholipids of an unknown sample are saponified, the composition of the resulting PLFA can be compared to the PLFA of known organisms to determine the identity of the ...
In 2018, a group from the University of Groningen managed to produce a large amount (30% of total phospholipids) of true archaeol-based phospholipid in transgenic E. coli. They found that the modified cells show higher tolerance to heat and cold. The result builds on top of their earlier 2015 attempt, which produced only a minuscule amount. [11]
Airbags, advanced driver assistance features, and high-strength materials mean that the safest cars today are far better at protecting people from injuries than ever before. Although most new cars ...
Theodore Gobley (1847) discovered phospholipids in mammalian brain and hen egg, called by him as "lecithins". Thudichum discovered in human brain some phospholipids , glycolipids (cerebroside) and sphingolipids (sphingomyelin). [9] The terms lipoid, lipin, lipide and lipid have been used with varied meanings from author to author. [15]
