The amino acids are acidic, basic and neutral based on the number of

Based on the number of amino groups and carboxyl groups amino acids are classified into acid amino acids, basic amino acids and neutral amino acids. Acidic amino acids have more number of carboxylic groups compared to amino groups. Example, aspartic acid. Basic amino acids have more number of amino groups compared to carboxylic groups. Example, lysine. Neutral amino acids have equal number of amino and carboxylic groups. Example, valine.
