The formation of the ether bond in mammals requires two enzymes, dihydroxyacetonephosphate acyltransferase (DHAPAT) and alkyldihydroxyacetonephosphate synthase (ADAPS), that reside in the peroxisome. [8] Accordingly, peroxisomal defects often lead to impairment of ether-lipid production.
The structure of this lipid differs in plants and animals, regarding fatty acid composition. In addition, phosphatidylserine plays an important role in the human brain content, as it makes up 13–15% of the phospholipids in the human cerebral cortex. This lipid is found in a wide range of places.
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.
Membrane lipids are a group of compounds (structurally similar to fats and oils) which form the lipid bilayer of the cell membrane. The three major classes of membrane lipids are phospholipids, glycolipids, and cholesterol. Lipids are amphiphilic: they have one end that is soluble in water ('polar') and an ending that is soluble in fat ...
Phosphatidylserine (PS) is the major acidic phospholipid class that accounts for 13–15% of the phospholipids in the human cerebral cortex. [7] In the plasma membrane, PS is localized exclusively in the cytoplasmic leaflet where it forms part of protein docking sites necessary for the activation of several key signaling pathways.
Alkylglycerol monooxygenase (AGMO) (EC 1.14.16.5) is an enzyme that catalyzes the hydroxylation of alkylglycerols, a specific subclass of ether lipids.This enzyme was first described in 1964 as a pteridine-dependent ether lipid cleaving enzyme. [1]
Jason Edwards scored 18 points and Jaylen Carey had a double-double as host Vanderbilt held on to upset sixth-ranked Tennessee 76-75 on Saturday in Nashville, Tenn.
The surface of a curved lipid bilayer. Lipidology is the scientific study of lipids. Lipids are a group of biological macromolecules that have a multitude of functions in the body. [1] [2] [3] Clinical studies on lipid metabolism in the body have led to developments in therapeutic lipidology for disorders such as cardiovascular disease. [4]
