According to biochemical classification of amino acids valine is ____ ?
A
with non polar side chain
B
with polar side chain
C
with positive side chain
D
with negative side chain
Explanation: 

Detailed explanation-1: -Valine is another simple amino acid with just an isopropyl variable group. Just like alanine, we see nothing but carbon and hydrogen, making valine a non-polar hydrophobic amino acid.

Detailed explanation-2: -The non-polar amino acids (shown here) include: alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, tryptophan, tyrosine and valine.

Detailed explanation-3: -According to the structure of valine, the side chain of valine is basically a non-polar isopropyl group.
