Distribution of Phosphorous in Pyloric Coeca

Abstract

The authors studied the distribution of phoshorous in pyloric coeca of skipjack, and obtained the following results.
1) The total phosphorous content was about 130mg%, inorganic phosphorous 48mg% and organic phosphorous 82mg%-lipoid phosphorous 5mg%, nucleic-acid phosphorous 37mg% and phosphoprotein phosphorous 2mg%, respectively, in the organic phosphorous.
2) The amount of lipoid phosphorous did not change by storing, but nucleic-acid and phosphoprotein phosphorous decreased rapidly with the lapse of time.
3) Pyloric coeca contained much more organic phosphorous and less lipoid phosphorous as compaired with the muscle of skipjack.
