POLAROGRAPHY OF BIOLOGICAL PURINES AND PYRIMIDINES

Polarography of biological purines and pyrimidines.

Since electron-transfer reactions are so important in biological systems, information which can be obtained in respect to the energy levels (electrical potentials) and reaction pathways involved should be helpful in the understanding, control and utilization of such reactions. Polarographically determinded half-wave potentials ( and electrode reaction paths or mechanisms readily provide such da...

Nucleotide Metabolism – Purines and Pyrimidines

Nucleotide metabolism results in the synthesis of the four nucleotides that form DNA. These are further divided in two categories: purines and pyrimidines. Their construction and degradation takes place in a progression of single steps, while different enzymes and cofactors are involved in the process. Beside degradation, there is also a form of reprocessing purine and pyrimidine nucleotides, d...
