Ok so I am doing a presentation on the caffeine molecule and I can't figure out the systematic name
1,3,7-Trimethyl-3,7-dihydro-1H-purine-2,6-dione

I can find the 1,3,7-trimethyl I know its made up of a purine base, but after that I am lost, 3,7 dihydro, 1H-, and the 2,6-dione I have no idea where they come from.

Also the functional groups; I keep seeing people say they are amide, amine, and alkene, but what about ketone, the 2,6-dione means theres a ketone because of the 2-6 -one?

Any help would be greatly appreciated.
Thanks

The 2,6-dione groups are the ketone groups attached to either side of the purine ring. As for the hydro groups, I have no clue, sorry.

do the ketone groups overlap the amide groups?
