Nucleotides of human blood platelets

Abstract

Platelets were isolated from normal human blood and the following constituents found in the approximate concentrations given as percentage of total nitrogen: 80-90% in protein; 0.1% in the nucleic acid fraction; 12% in adenosine diphosphate plus adenosine triphosphate; 1.8% in adenine, guanine, cytosine and uracil, as ribose phosphates in undetermined combination. Traces of deoxyribose were detected in human blood platelets.
