WebAsparagine N (Asn) Chemical Properties: Neutral. (Amides of acidic amino acids R-group) Physical Properties: Polar (uncharged) Asparagine is the amide of aspartic acid. The amide group does not carry a formal charge under any biologically relevant pH conditions. The amide is rather easily hydrolyzed, converting asparagine to aspartic acid. WebPolar basic (+ve charged) amino acids. 3 amino acids are polar basic: lys, arg, his. Lys and arg have functional groups that are +vely charged at pH 7. The lys has an amino group with a high pK 10.0 so at pH 7.4 this group is protonated. Opposite is lys. The group on top with red oxygens is the alpha carboxyl group. WebThese compounds are known as a-amino acids because the -NH 2 group is on the carbon atom next to the -CO 2 H group, the so-called carbon atom of the carboxylic acid.. Zwitterions.
