Answer 1

Aspartate and Glutamate

There are different categories in the amino acids, one of them are the negative amino acids, characterized by having an carboxylic acid in the R group, that under the right conditions can be deprotonated and thus the amino acid will have negative charge. The two amino acids on this gu¿oup are glutamate and aspartate.
