Carboxylic acids and esters are one of the most important classes of organic compounds. They are everywhere:
* in food (citric acid; vinegar = a solution of acetic acid);
* in medicines (aspirin = acetylsalicylic acid);
* in fats (triglycerides are esters of fatty acids and glycerol);
* in plastics (polyesters);
* in biochemistry (transformation of pyruvate through the citric acid cycle);
* and even in ants :) (formic acid)
