SUMMARY
The acidity and basicity of amino acids are primarily determined by their functional groups. In amino acids, the acidic group is identified as the NH3+ (ammonium ion), while the basic group is the COO- (carboxylate ion). This distinction is crucial for understanding their behavior in aqueous solutions, where individual amino acids exist as zwitterions. The concept of conjugate acids and bases is essential for grasping these interactions, as it highlights how proton transfer influences the acid-base properties of amino acids.
