What is Acidic amino acids are and explain in detail?
aspaic acid and glutamic acid are proton donors. At physiologic pH, the side chains of these amino acids are fully ionized, containing a negatively charged carboxylate group (-COO-). They are, therefore, called aspaate or glutamate to emphasize that these amino acids are negatively charged at physiologic pH Asparagine and Glutamine are neutral amino acids.
