Adenine vs Purine - What's the difference?

adenine | purine |

Adenine is a see also of purine.


As nouns the difference between adenine and purine

is that adenine is (biochemistry|genetics) a base, c5h5n5, found in certain glands and tissues, which pairs with thymine in dna and uracil in rna while purine is (chemistry) any of a class of organic heterocyclic base containing fused pyrimidine and imidazole rings; they are components of nucleic acids.

    Noun

    (en noun)
  • (organic compound) Any of a class of organic heterocyclic compounds composed of fused pyrimidine and imidazole rings that comprise one of the two groups of organic nitrogenous bases (the other being the pyrimidines) and are components of nucleic acids.

  • Clifford et al.'' (1976) investigated the metabolism of individual purines''' and found that adenine, and to a lesser extent hypoxanthine, had pronounced effects on blood uric acid levels. The ' purine content of foods, in particular adenine, would therefore be of immense nutritional significance.

  • For example, for purine'-pyrimidine and for pyrimidine-'''purine''' base steps the presence of ' purines on opposite strands in successive base pairs sterically restricts the conformations that these base pairs can adopt relative to each other.

  • The discovery that certain pyrazolopyrimidine nucleobases and nucleosides, analogs of naturally occurring purines', are toxic to ''Leishmania'', coupled with the obligatory nature of the leishmanial '''purine''' salvage pathway, has spawned considerable interest in the ' purine salvage pathway as a drug target.
