WebApr 29, 2016 · Oils in the form of triacylglycerols are the most abundant energy-dense storage compounds in eukaryotes, and their metabolism plays a key role in cellular energy balance, lipid homeostasis, growth, and maintenance. Plants accumulate oils primarily in seeds and fruits. Plant oils are used for food an … In an organic chemistry general sense, an ether lipid implies an ether bridge between an alkyl group (a lipid) and an unspecified alkyl or aryl group, not necessarily glycerol. If glycerol is involved, the compound is called a glyceryl ether, which may take the form of an alkylglycerol, an alkyl acyl glycerol, or in combination with a phosphatide group, a phospholipid.

WebApr 30, 2024 · Soya beans contain a variety of lipids, and it is important to selectively separate neutral lipids from other lipids. Supercritical carbon dioxide extraction has been used as an alternative to the selective separation of neutral lipids from soya beans, usually using non-polar hexane. However, supercritical carbon dioxide extraction has a high … 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.
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.
