A Google Scholar search for "molybdenum purine" will come up with many studies discussing how molybdenum is involved in purine catabolism. For example, the following article states "[molybdenum] is considered essential because it is part of a complex called molybdenum cofactor that is required for the three mammalian enzymes xanthine oxidase (XO), aldehyde oxidase (AO), and sulfite oxidase (SO). XO participates in the metabolism of purines". (https://aspenjournals.onlinelibrary.wiley.com/doi/abs/10.117...).
When I was younger I was able to drink multiple pots of coffee in a day and even drink coffee right before going to sleep without any obvious issues.
