Turnover of Acid-Soluble Phosphorus in the Liver

The investigation of Kaplan and Greenberg (103) showed that the maximum content of the free phosphate of liver tissue of fasting rats reaches its maximum 75 minutes after intraperitoneai injection of labeled phosphate, while the maximum activity of the total acid-soluble phosphorus is obtained after a lapse of 110-120 minutes (see Fig. 1). 

The effect of dietary state of the animal on the distribution of acid-soluble and P in the liver both of animals receiving only and those receiving P and 300-400 mg. glucose as well is seen in Table VII.

Curve 1, total acid-soluble P 2, inorganic P 3, alcohol precipitate 4, labile P in adenosine tripliosphate 5, nonlabile P in adenosine triphos-pliate 6, Hg precipitate 7, reeidiial P 8, Pi) precipitate. The points at 105 minutes are an average of ten delermimitioris.
