Glycerophospholipids are derived from glycerol-3-phosphate in a de novo pathway. [3] The term glycerophospholipid signifies any derivative of glycerophosphoric acid that contains at least one O-acyl, or O-alkyl, or O-alk-1'-enyl residue attached to the glycerol moiety. [4] The phosphate group forms an ester linkage to the glycerol.
Examples of glycerophospholipids found in biological membranes are phosphatidylcholine (also known as PC, ... Molecular Biology and Cell Biology; Nomenclature.
Example of an ethanolamine plasmalogen with the characteristic vinyl ether linkage at the sn-1 position and an ester linkage at the sn-2 position. Plasmalogens are a class of glycerophospholipid with a plasmenyl group linked to a lipid at the sn-1 position of the glycerol backbone.
The primary saponifiable lipids are free fatty acids, neutral glycerolipids, glycerophospholipids, sphingolipids, and glycolipids. [ 1 ] By comparison, the non-saponifiable class of lipids is made up of terpenes, including fat-soluble A and E vitamins, and certain steroids, such as cholesterol.
In contrast, conventional glycerophospholipids and triglycerides are triesters. [1] Structural types include: Ether phospholipids: phospholipids are known to have ether-linked "tails" instead of the usual ester linkage. [1] Ether on sn-1, ester on sn-2: "ether lipids" in the context of bacteria and eukaryotes refer to this class of lipids.
For example, green tea contains a particularly powerful compound called epigallocatechin gallate (EGCG), which has been found to help manage inflammation by influencing how the body manages ...
For example, the melting temperature of di-oleoyl-phosphatidylethanolamine is -16 °C while the melting temperature of di-oleoyl-phosphatidylcholine is -20 °C. If the lipids had two palmitoyl chains, phosphatidylethanolamine would melt at 63 °C while phosphatidylcholine would melt already at 41 °C. [ 4 ]
Most claims about the dangers of seed oils tend to focus at least in part on inflammation — more specifically, that seed oils contain large amounts of omega-6s relative to omega-3s.
