N9glycosidic
N9glycosidic refers to a type of glycosidic bond where a sugar molecule is attached to a nitrogen atom at the ninth position of a purine or pyrimidine base. This specific linkage is fundamental to the structure of nucleic acids, namely DNA and RNA. In these biomolecules, the nitrogenous bases adenine, guanine, cytosine, thymine, and uracil are connected to the sugar moiety (deoxyribose in DNA, ribose in RNA) via an N9glycosidic bond.
This bond is formed between the C1' carbon of the sugar and the N9 atom of the
The N9glycosidic bond is crucial for the genetic code. Its stability and specific orientation allow for the
