Unformatted text preview: Carboxylic Acid Natural Products Carboxylic acids are widespread in nature, often combined with other functional groups. Simple alkyl carboxylic acids, composed of four to ten carbon atoms, are liquids or low melting solids having very unpleasant odors. The fatty acids are important components of the biomolecules known as lipids , especially fats and oils. As shown in the following table, these long-chain carboxylic acids are usually referred to by their common names, which in most cases reflect their sources. A mnemonic phrase for the C 10 to C 20 natural fatty acids capric, lauric, myristic, palmitic, stearic and arachidic is: " C urly, L arry & M oe P erform S illy A ntics" (note that the names of the three stooges are in alphabetical order). Interestingly, the molecules of most natural fatty acids have an even number of carbon atoms . Analogous compounds composed of odd numbers of carbon atoms are perfectly stable and have been made synthetically. Since nature makes these long-chain acids by odd numbers of carbon atoms are perfectly stable and have been made synthetically....
