The general structure of alpha amino acid can be represented as
Which amino acid is not correctly matched with R-given?

• A

  $\mathrm{R}=-\mathrm{CH}_2-\mathrm{C}_6 \mathrm{H}_4-\mathrm{OH}(\mathrm{p})-$ (Tyrosine)
• B

  $\mathrm{R}=-\mathrm{CH}_2-\mathrm{SH} \quad-$ (Cysteine)
• Correct answer
  C

  $\mathrm{R}=-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{S}-\mathrm{CH}_3-$ (Serine)
• D

  \(\mathrm{R}=-\mathrm{CH}_2-\underset{\substack{|| \\ \large \mathrm{O}}}{\mathrm{C}}-\mathrm{NH}_2\) - (Asparagine)

Hence, the correct answer is option: 'C'.
