Saturated fatty acids
General formula of saturated fatty acids is CH3 (CHI), COOH. It has a polar end with a free XOOH group and a non-polar end with a hydrocarbon chain, as can be seen in the structure of fatty acid illustrated in Figure 2.2. Fatty acids with less carbon atoms are readily xiscible with water and the solubility decreases with an increase in carbon atoms. Saturated fatty acids with less than 10 carbon atoms are liquid at room temperature and more are solids. Melting point of these fatty acids increases with increasing number of carbon atoms.
