We may conclude from this that the doable linkage in the oleic acid of tlr

the pig's liver may be a< unted for, in other words, by supposing tl ation 



of Btearic acid and of the ordinary (depot) oleic acid 



double link between the Bixth and seventh carb d i thes). E 



other double links may. however, be introduced into the fatty-acid chain, ( tho

To go into these chemical problems any further here would l>e <>nt 

 place. One other fact, should, however, 1"' borne in mind- namely, that 

 the unsaturated acids may lie formed from saturated acids throng 

 intermediate formation of /8-hydroxy and /S-ketonic acids. Their m 

 presence, in other words, should no1 be taken as evidence that the oxida- 

 tion of fatty acids is initialed by the introduction of an hydroxy] gTOup
