C07H SUGARS; DERIVATIVES THEREOF; NUCLEOSIDES; NUCLEOTIDES; NUCLEIC ACIDS (derivatives of aldonic or saccharic acids C07C, C07D; aldonic acids, saccharic acids C07C59/105, C07C59/285; cyanohydrins C07C255/16; glycals C07D; compounds of unknown constitution C07G; polysaccharides, derivatives thereof C08B; DNA or RNA concerning genetic engineering, vectors, e.g. plasmids, or their isolation, preparation or purification C12N15/00; sugar industry C13)
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.
