They suggest that the osidntioii procecds a t alteriintc carbon ntonis along tile wliolc clinki of the moleculc at the p, 6 ctc. positions, thougli tlic possibility of an a-y type playing a sccondnry part cannot bc altogetlicr ruled out, but if it csists at :ill, it is less important. A glancc n t the iibovc forniuln will sliow how this multiplc alteriintc oxidation theory if it is t,rue, csplains (1) why no iutcrmciliate kctonc bodics with inore thnu 4 carbon atoms are ever found, (2) why butyric acid is not an interiucdiate in thc osidntion, iind (3) why inore ketone bodics are obtained from h i g h ncids thnn from butyric.
A further type of osidation lins rccently been invcstigated by Vcrkndc, wlio has nindc :L grcat contribution to our knowledge of fat inctabolisin by his discovcry of w-oxidation. He has fouiid that when ccrtain fntty acids arc fed to auininls tlic corresponding or dcrivcd dibasic acids can Le fouiid in the uriiic showing that oxidation of the tcrniinnl cnrbon atoms is nlso possible. Thus if tlic C,, acid is fed, thc C8 and C, dibasic acids are found in the uriiic, or if n C,,acid is given, the Co aid C, dibasic dcrivntives result.
