WebATP is another type of nucleic acid and hence it is structurally very similar to the nucleotides that make up DNA and RNA It is a phosphorylated nucleotide Adenosine (a nucleoside) can be combined with one, two or three phosphate groups One phosphate group = adenosine monophosphate (AMP) Two phosphate groups = adenosine diphosphate (ADP) WebMay 12, 1998 · A catalytic strategy used by many enzymes is to use nucleotide triphosphates, in particular ATP, for leaving group activation. In general, this strategy can be accomplished by transfer of the γ-phosphoryl group of the nucleotide to the substrate. The resulting phosphorylated intermediate decomposes into phosphate and product.

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.
