Hi,
I started studying organic chemistry and now doing exercise questions for nomenclature.
Now I'm stuck with this question for 2 hours.
Carboxylic acid will be the suffix here.
At the other end, there is primary amide.
But the name for this is 5-amino-5oxopentanoic acid not 5-carbamoylpentanoic acid.
Why is amide sperated as amine and ketone here?
I tried to find if there was a rule about it but I couldn't find any information :/
Can someone explain it please?

This name is made up as if the compound were a monocarboxylic acid. Officially, IUPAC allows the names glutaramic acid (Rule C-431.1) and 4-carbamoylbutanoic acid (Rule C-431.4) as synonyms.

I really appreciate your answer. Thank you!
So is it okay to state amide separately as ketone and amine when it is not the priority functional group?
