As we know that, after digestion of proteins, it converts into amino acid. Does this amino acid have any property of acids? If no then why it is named as acid?

general formula of amino acids is   H₂N-CH-COOH ,

                                                          l

                                                          R

 

where Rcan be different functional group for different amino acids .

amino acids exists as neutral,they dont show properties of acids but ,they are known as acids because of the presence of COOH group.

They can be acidic depending on the R group attached.That you will learn in your higher classes.
