ACIDIC degradation has been widely used to determine the distribution of the pyrimidine nucleotides in ... the first stage is the hydrolysis of the purine glycosidic linkages to give apurinic ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...
