Question

Select the correct set of answer.

Column I		Column II
A	Tyrosine	P	Essential amino acid
B	Serine	Q	Ceric ammonium nitrate
C	Tryptophan	R	Neutral $FeCl _{3}$
D	Proline	S	Carbylamine test - Negative

• A. A-R, B-Q C-P, D-S
• B. A-Q B-R, C-S, D-P
• C. A-R, B-P, C-Q, D-S
• D. A-S, B-Q, C-P, D-R

Answer 1

Answer: (A)

(A) Tyrosine $\rightarrow$ Tyrosine gives neutral $FeCl _{3}$ test.
(B) Serin $\rightarrow$ It contains alcohol group $(- OH )$ and thus will give positive test on reaction with Ceric ammonium nitrate.
(C) Tryptophane $\rightarrow$ An essential amino acids needed for normal growth in infants and for nitrogen balance in adults.
(D) Proline $\rightarrow$ It contains secondary amine group and thus does not give positive carbytl amine test.
