Question 2 - 2021 (17 Mar Shift 1)
Which of the following is correct structure of tyrosine?
(a) Structure with $\text{H}_2\text{N}$, $\text{COOH}$, $\text{H}$ on chiral center and $\text{CH}_2$-indole-$\text{OH}$ side chain (b) Structure with $\text{H}_2\text{N}$, $\text{COOH}$, $\text{H}$ on chiral center and a direct phenol-$\text{OH}$ side chain (c) Structure with $\text{H}_2\text{N}$, $\text{COOH}$, $\text{H}$ on chiral center and $\text{CH}_2$-naphthalene-$\text{OH}$ side chain (d) Structure with $\text{H}_2\text{N}$, $\text{COOH}$, $\text{H}$ on chiral center and $\text{CH}_2$-para-hydroxyphenyl side chain
Show Answer
Answer: (d)
Solution
The structure of tyrosine amino acid has $\text{H}_2\text{N}$, $\text{COOH}$, and $\text{H}$ on the chiral center with a $\text{CH}_2$-para-hydroxyphenyl side chain. Tyrosine is 4-hydroxyphenylalanine.
