Answer:
The given three amino acids are polar in nature.
Explanation:
The structure of amino acid is generally composed of four parts:
1. Carboxylic group
2. Amino group
3. Hydrogen atom
5. Alkyl or Aryl group
The central carbon atom also known as alpha carbon which is surrounded by amino group on one side, H atom on top, Amino group on right side and Alkyl or Aryl group on down side.
The R group given amino acids are as,
Tyr = -CH₂-Ph-OH
Asn = -CH₂-COO-NH₂
Thr = -CH(OH)-CH₃
Hence, due to presence of Hydroxyl groups and Amine groups on Alkyl or Ary l chain the given three amino acids get polar in nature.
