Über den Gehalt der Organe an Purin-Nucleotiden, -Nucleosiden und freien Purinen

Abstract
Usually the nucleic acid purine represents less than 10% of the total purine in striated muscle, the soluble purine more than 90%. Kidney, brain, liver, spleen, pancreas, and thymus follow, in order of decreasing % of soluble purine. In nucleated avian erythro-cytes the soluble purines make up 1/3 of the total purines; in all tissues in which glycolysis and phosphorylative reactions play a leading role, they are especially high. Human tumors show a high soluble purine fraction; exptl. tumors show lower values.
