Lysine (positively charged amino acid)
<u>It is present on the outside of a globular protien.</u>
Explanation:
<u>Formula of lysine:</u>
C6H14N2O2
Globular proteins are folded such that their tertiary structure consists of the polar, or hydrophilic, amino acids arranged on the outside and the nonpolar, or hydrophobic, amino acids on the inside of the three-dimensional shape. This arrangement is responsible for the solubility of globular proteins in water.
<u>As lysine is a positively charged polar / hydrophilic amino acid , it is arranged on the outside of the globular protien.</u>
