Description

C07H encompasses the chemistry of monosaccharides, disaccharides, and polysaccharides, along with their synthetic derivatives and chemical modifications. This subclass also covers nucleosides (sugar-base conjugates), nucleotides (phosphorylated nucleosides), and nucleic acids (DNA, RNA, and analogues), including their isolation, synthesis, and structural characterization. The classification includes oligonucleotides, modified nucleotides, and sugar-nucleoside conjugates used in therapeutic, diagnostic, or research applications. Adjacent carbohydrate chemistry not involving nucleoside/nucleotide components falls under C07C or C07G.

Scope Notes

Glossary: Heterocyclic radical or hetero ring heterocyclic radical heterocyclic radicals hetero ring hetero rings These are considered to exclude saccharide radicals as defined above. Polysaccharide polysaccharides A compound having more than five saccharide radicals attached to each other by glycosidic linkages. Saccharide radical saccharide radicals Radical derived from acyclic polyhydroxy-aldehydes or acyclic polyhydroxy-ketones, or from their cyclic tautomers, by removing hydrogen atoms or by replacing hetero bonds to oxygen by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium or tellurium, in accordance with either of the following definitions: a) It consists of an uninterrupted carbon skeleton and oxygen atoms directly attached thereto, and is considered to be terminated by every bond to a carbon atom of a cyclic structure and by every bond to a carbon atom having three bonds to hetero atoms, e.g. ester or nitrile radicals, and contains within the carbon skeleton an unbranched sequence of at the most six carbon atoms in which at least three carbon atoms - at least two in the case of a skeleton having only four carbon atoms - have one single bond to an oxygen atom as the only hetero bond, and (i) in a cyclic or acyclic sequence, at least one other carbon atom has two single bonds to oxygen atoms as the only hetero bonds, or (ii) in an acyclic sequence, at least one other carbon atom has one double bond to an oxygen atom as the only hetero bond, the said sequence containing at the most one double bond, i.e. C=C or possibly ketalised C=O, in addition to the hetero bonds mentioned under (i) or (ii). b) It is also a radical derived from a radical defined in (a) by replacing at the most four of the specified hetero bonds to oxygen by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium or tellurium. | Limiting references: Derivatives of aldonic or saccharic acids , Aldonic acids, saccharic acids , Cyanohydrins Glycals Compounds of unknown constitution, glycosides Steroid glycosides Polysaccharides, derivatives thereof DNA or RNA concerning genetic engineering, vectors, e.g. plasmids, or their isolation, preparation or purification Using enzymes or microorganisms for the preparation of compounds containing saccharide radicals | Application references: Sugar industry
