8-Hydroxy-2'-Deoxyguanosine
Common oxidized form of deoxyguanosine in which C-8 position of guanine base has a carbonyl group.
Year introduced: 2020(1985)
Purines
A series of heterocyclic compounds that are variously substituted in nature and are known also as purine bases. They include ADENINE and GUANINE, constituents of nucleic acids, as well as many alkaloids such as CAFFEINE and THEOPHYLLINE. Uric acid is the metabolic end product of purine metabolism.
Purine Nucleosides
Purines with a RIBOSE attached that can be phosphorylated to PURINE NUCLEOTIDES.
Year introduced: 1974
Nucleic Acids, Nucleotides, and Nucleosides
Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges).
Year introduced: 1998
Nucleosides
Purine or pyrimidine bases attached to a ribose or deoxyribose. (From King and Stansfield, A Dictionary of Genetics, 4th ed)
Heterocyclic Compounds, 2-Ring
A class of heterocyclic compounds that include a two-ring fused structure. Both aromatic and non-aromatic ring structures are included in this category.
Heterocyclic Compounds
Cyclic compounds that include atoms other than carbon in their ring structure.
Guanosine
A purine nucleoside that has guanine linked by its N9 nitrogen to the C1 carbon of ribose. It is a component of ribonucleic acid and its nucleotides play important roles in metabolism. (From Dorland, 28th ed)
Year introduced: 1972
Deoxyribonucleosides
A purine or pyrimidine base bonded to DEOXYRIBOSE.
Year introduced: 1973
Deoxyguanosine
A nucleoside consisting of the base guanine and the sugar deoxyribose.
Year introduced: 1978
Heterocyclic Compounds, Fused-Ring
Multiple ring heterocyclic compounds containing two or more rings that share two atoms and one bond in common.
Year introduced: 2017
