Given their importance in the cell, the synthesis and degradation of nucleoside triphosphates is under tight control. This section focuses on nucleoside triphosphate metabolism in humans, but the process is fairly conserved among species. Nucleoside triphosphates cannot be absorbed well, so all nucleoside triphosphates are typically made de novo.
