The  three  molecules  of  hydroxyl  in  the  glycerin  are  easily  substi- 
tuted by  several  elements  or  compounds,  such  as  acetic,  benzoic,  hydro- 
chloric, hydrobromic  and  other  acids;  to  illustrate  this  I  give  below 
the  molecular  position  of  mono-,  di-  and  tri-chlorhydrins :

In  the  fats  and  oils,  however,  the  molecules  of  hydroxy  1  of  the 
glycerin  are  substituted  by  the  radicals  of  the  fatty  acids,  such  as 
stearyl,  palmityl  and  oleyl,  producing  ethers,  as  which  fats  and  oils 
must  be  viewed,  as  for  instance : 
Stearins  or  Propenyl  tristearyls  =  C3H5.3(Ci8H3503) 
Oleins  or  Propenyl  trioleyls  =  C3H5.3(Ci8H3302) 
Again,  as  stearic,  palmitic  and  oleic  acids  are  acids  derived  from 
stearyl,  palmityl  and  oleyl,  and  have  an  analogous  constitution,  the 
former  belonging  to  the  series  of  formic  and  the  latter  to  that  of  acry- 
lic acids,  their  relative  constituents  must  be  grouped  as  follows :
