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.
