The most common is oxidation of unsaturated lipids by atmospheric oxygen, rancidification. ... Lipidomics reveals that adiposomes store ether lipids and mediate phospholipid traffic. J Lipid Res 48: 837 ... WebTriacylglycerols (TAGs), steryl esters (SEs) and wax esters (WEs) form the group of neutral lipids. Whereas TAGs are present in all types of cell, the occurrence of SEs in prokaryotes is questionable, and the presence of WEs as storage molecules is restricted to plants …
Web1986). Harvey et al. (1986) examined the degradation of both, a glycosidic ether lipid and ester-bound phospholipids. Based on their findings, the authors assumed that intact po-lar lipids with glycosidic head groups show a higher stability against degradation than intact polar lipids with phosphoester head groups. WebEther Lipid. Ether Lipids: While in the acylglycerols the fatty acids are linked to the glycerol moiety by a ester linkage in glycerol ethers the fatty acids are linked to the glycerol by an ether linkage. ... as some rearrangement or other degradation may occur.

WebDec 19, 2000 · This degradation technique cleaves ether bonds and thus releases the carbon skeletons of the GDGTs as alkyliodides (e.g., refs. 8 and 9). Subsequently, ... Combined with the fact that cultured archaea exclusively biosynthesize isoprenoid ether lipids, it suggests that GDGTs X–XII are derived from nonthermophilic eubacteria, which … WebDec 1, 2013 · However, there are drawbacks using GC–MS and NP-APCI-MS for glycerol ether lipid analysis. First, both are suitable for the analysis of CLs but cannot directly allow analysis of IPLs without prior head group cleavage. Moreover, APCI causes in-source degradation of ether lipids to a varying degree, depending on CL structures.
