structure of GTP

1.	structure of GTP
Answer» Guanosine triphosphate (GTP) is a guanine\xa0nucleotide\xa0containing three phosphate groups esterified to the sugar moiety.\xa0GTP\xa0functions as a carrier of phosphates and pyrophosphates involved in channeling chemical energy into specific biosynthetic pathways.\xa0GTP\xa0is involved in energy transfer within the cell. For instance, a\xa0GTP\xa0molecule is generated by one of the enzymes in the citric acid cycle. This is tantamount to the generation of one molecule of\xa0ATP, since\xa0GTP\xa0is readily converted to\xa0ATP\xa0with nucleoside-diphosphate kinase (NDK).
