When a peptide is hydrolysed Aspartate is found, but as far as I understand that doesnt mean that Aspartate was in the peptide, but another amino acid could have transformed into Aspartate. Is it possible to know which amino acid? To me the most similar one is Asparagine.

1) What type of chemical bond is broken when a peptide is hydrolyzed? What is the general reaction and what are the products of that reaction?

2) Where does that type of bond exist in the sidechains of naturally occurring amino acids? What product(s) would you get from performing the reaction on those sidechains as well as the backbone of the peptide?

Yes, Asn also forms Asp during hydrolysis.

Kork, If you find glutamate after hydrolyzing a peptide, what does that suggest to you?

[Kork]

I dont still dont get it.

Maybe we should go back to aspartate for a moment.  Did you understand that, or are you still unsure about what people said?
