Читать книгу Plant Nucleotide Metabolism - Hiroshi Ashihara - Страница 16

A nucleoside consists of a nucleobase and a five-carbon sugar (ribose or deoxyribose). Adenosine (14), guanosine (15), inosine (16), and xanthosine (17) are catabolites of purine ribonucleotides and RNA while deoxyadenosine (18) and deoxyguanosine (19) are catabolites of DNA. Cytokinins also occur as ribosides, namely, isopentenyladenine riboside (20), benzyladenine riboside (21), and trans-zeatin riboside (22) (Ashihara et al. 2013).
