1 All of the statements about the classification of these am

1 All of the statements about the classification of these amino acids are correct EXCEPT:

a.

Aspartic acid and asparagine are acidic amino acids.

b.

Alanine and valine are neutral, nonpolar amino acids.

c.

Serine and glutamine are polar, uncharged amino acids.

d.

Lysine and arginine are basic amino acids.

e.

Tyrosine and phenylalanine are aromatic amino acids.

Solution

The statement is incorrect.

Aspartic acid is a polar acidic amino acid.

Asparagine is a neutral polar amino acid.

Alanine and valine are non-polar aliphatic amino acid.

Serine and glutamine are polar neutral amino acids.

Lysine and arginine are basic polar amino acids.

Tyrosine and phenylalanine are aromatic non-polar amino acids.

Thus, this states that choice A is correct answer since asparagine is not an acidic amino acid. It is a neutral polar amide by chemical nature.
