Nucleotides and nucleotide sugars in human blood cells. II. Group "O"
A study of nucleotides and nucleotide sugars in human blood cells has been carried out. Ten samples from healthy yound people of group "O" were analyzed by ion-exchange chromatography, and the following nucleotides and nucleotide sugars were found: NAD+; UDP-glucose, UDP-mannose, UDP-galac...
