============

Layer lipids of Archaea are exceptional and distinct rom those found in Eukarya and Bacteria. The polar lipids comprise of isoprenoid chains, 20–40 carbons long and generally soaked, which are joined by means of stable ether bonds to the glycerol carbons at the sn‐2,3 positions. Polar head bunches contrast at the variety level of assorted qualities and comprise of blends of glyco gatherings (for the most part disaccharides), or potentially phospho amasses fundamentally phosphoglycerol, phosphoserine, phosphoethanolamine or phosphoinositol. Phosphocholine headgroups are once in a while found. To a great degree halophilic archaea are portrayed by headgroups comprising of phosphoglycerolphosphate‐O‐methyl, and sulfated‐sugars. Some of these archaea integrate cardiolipin analogs. The intrinsic dependability and remarkable components of archaeal lipids makes them a valuable biomarker for Archaea inside ecological specimens, including sea residue. The polar lipids of Archaea can be utilized to make liposomes (shut vesicles alluded to as archaeosomes) with qualities that are valuable for applications in biotechnology. Archaeal‐like polar lipids are being integrated to upgrade the properties of archaeosomes to serve as next‐generation adjuvants and medication conveyance frameworks.
