ACETATE CARBON ("C) INTO TISSUE FRACTIONS 411 C O <_) 2000 Liver Conrrol Di nit rocyc I openryl phenol t500 - 000 500-. 60 mm. Fig. 1. Effect of dinitro-cyclo-pentylphenol on the incorporation of i*C into total fats (a) and total tissue (b) of the liver of the mouse, "C injected as CHgWCOONa. is metabolized at a slower rate than acetate and correspondingly in the left part of the curve the acetate values are higher, in the right part of the curve the succinate values are higher (2). A similar trend as indicated by the curves plotted in Fig. la is shown by the curves seen in Fig. 16 in which the specific activity of the dry liver tissue is plotted as function of time, both for controls and injected animals. The ^^C-content of the liver tissue except in a very early phase is mainly due to its fatty components but some is still pre- sent in acetic acid and other acid soluble tissue components, and to a very restricted extent in glycogen and in proteins. That the absolute i^C content of the total tissue is much smaller than that of the fatty components, is due to the dilution of highly active ftitty acids ])y large amounts of slightly active tissue Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hevesy, Georg von, 1885-1966.
