  <name>Esters</name>
  <description>Esters is a member of the class of compounds known as cholesteryl esters. Cholesteryl esters are compounds containing an esterified cholestane moiety. Esters is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Esters can be found in pineapple, which makes esters a potential biomarker for the consumption of this food product. In chemistry, an ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O–alkyl (alkoxy) group. Usually, esters are derived from a carboxylic acid and an alcohol. Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of the main classes of lipids, and making up the bulk of animal fats and vegetable oils. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties .</description>
