Hydrogen bond donor and acceptor - chemicalize.org

Hi. I am a little unsure of how to interpret the count of the number of hydrogen bond donors and acceptors on chemicalize.org. Should I expect to see the letter D next to a donor and the letter A next to an acceptor? For all compounds I've looked up so far I've only seen an A next to an O or N atom, when I think they could be donors and not acceptors in some cases.

Are both strong and weak acceptors/donors shown?

Hi Deanna,

Currently we have a bug on chemicalize.org where we are not able to show donor sites on the generated images. We are looking into the issue and will keep you updated when we have results!

Cheers,

Andras
