Which lipid is most amphipathic? Lipids have been classified into eight categories by the Lipid MAPS consortium as follows: Fatty acids or fatty acid residues when they are part of a lipid are a diverse group of molecules synthesized by chain-elongation of an acetyl-CoA primer with malonyl-CoA or methylmalonyl-CoA groups in a process called fatty acid synthesis. They are made of a hydrocarbon chain that terminates with a carboxylic acid group; this arrangement confers the molecule with a polar hydrophilic end and a nonpolar Cell membranes contain a variety of biological molecules notably lipids and proteins. Composition is not set but constantly changing for fluidity and changes in the environment even fluctuating during different stages of cell development. Specifically the amount of cholesterol in human primary neuron cell membrane changes and this change in composition affects fluidity throughout development stages. Material is incorporated into the membrane or deleted from it by a variety of mechanisms: Lipid - Wikipedia Lipid metabolism - Wikipedia Amphiphile - Wikipedia Their amphipathic nature drives the formation of the lipid bilayer structure of membranes. The cell membrane seen under the electron microscope consists of two identifiable layers or "leaflets" each of which is made up of an ordered row of glycerophospholipid molecules. Membrane lipids are a group of compounds which form the double-layered surface of all cells. The three major classes...
