Structure and properties of fatty acids
WebThe simplest fatty acids are unbranched, linear chains of CH2 groups linked by carbon-carbon single bonds with one terminal carboxylic acid group. The term saturated indicates that the maximum possible number of hydrogen atoms are bonded to each carbon in the molecule.
