Derivatives
Derivatives of pyrimidone are the basis of many other biological molecules, including:
- Nucleobases, such as cytosine
- Barbiturates, such as metharbital
- Antiulcer drugs including temelastine, icotidine, donetidine, and lupitidine.
gollark: And if you've written the JSON database thing in the way everyone does it, it is opening the file, writing whatever array is in memory to that file, and closing it.
gollark: They create a temporary file, write their buffer to that, and then move the temporary file over the original, so that if they get interrupted in the middle of writing there's less chance of data loss.
gollark: Nope. No good text editor actually works like that.
gollark: I'm inferring.
gollark: Unless you've written more code than I assumed, it isn't actually doing that, it's rewriting the file with the entire array each time.
