Résumé

1. 1. The phosphoprotein and total phosphoinositide contents of solubilized erythrocyte membrane proteins were similar in human, dog, rabbit and sheep blood. Diphosphoinositide, a prominent component of human preparations, was found in trace quantities in the other species. The converse was true for phosphatidylinositol. 2. 2. During storage of human blood the triphosphoinositide was partially converted to diphosphoinositide. In stored dog blood the triphosphoinositide was degraded to phosphatidylinositol while little change was detected in rabbit blood. 3. 3. Solubilized membrane protein preparations from all species exhibited the same amino acid composition but there were differences in carbohydrate content. 4. 4. The polyphosphoinositides and phosphoproteins were metabolically active in all species.
