Lipids are composed of fatty acids and particularly, the lipids that constitute biological membranes are composed of long chain fatty acids. Long chain fatty acids, in order to be used for energy generation, membrane biogenesis, or signaling within the cell, need to be activated by esterification...
like carbohydrates,lipids are composed principally of carbon,hydrogen and oxygen,but they may also contain other elements,particularly phosphorus and nitrogen. 如糖类，脂类主要由碳，氢和氧，但它们也可以包含其他元素，特别是磷和氮。also lipids are not composedof repeating subunits and hence are not ...
Fats store energy and cushion organs, protecting them from damage, and are composed of fatty acids and glycerol, a sweet-tasting alcohol. Steroids contain four ring-shaped hydrocarbon molecules and include the dietary fat cholesterol as well as the sex hormones estradiol and testosterone. ...
Lipids are essential building blocks synthesized by complex molecular pathways and deposited as lipid droplets (LDs) in cells. LDs are evolutionary conserved organelles found in almost all organisms, from bacteria to mammals. They are composed of a hydrophobic neutral lipid core surrounding by a phosp...
Understanding membranes through the molecular design of lipids (This work has been featured on the Cover Page of the Journal) Lipids are amphiphilic molecules that are composed of hydrophilic and hydrophobic regions. A typical membranous aggregate (vesicles, water-filled lipid nan... S Bhattacharya,...

lipid structureStructure and properties of two representative lipids. Both stearic acid (a fatty acid) and phosphatidylcholine (a phospholipid) are composed of chemical groups that form polar “heads” and nonpolar “tails.” The polar heads are hydrophilic, or soluble in water, whereas the nonpolar...
Lipidsare integral molecules in the body’s structure, and they are important substrates for energy metabolism. Abnormalities in plasmalipidlevels (dyslipidemia), particularly cholesterol, have been associated with increased risk of cardiovascular disease. An individual’s plasmalipid profileis influenced by...
Diacylglyceryltrimethylhomoserine (DGTS) and diacylglyceryl hydroxymethyltrimethyl-β-alanine (DGTA) belong to a new type ofglycerolipids called betaine lipids, which are composed of diacylglycerol andN-permethylated hydroxyamino acids, that are linked by an ether linkage. Betaine lipids are widely dis...
