Vedclass · Answer

(C) The identification of amino acids based on functional group tests is as follows:$1$. Ester test: Serine $(Ser)$ contains a hydroxyl $(-OH)$ group,which can undergo esterification. Thus,$A-R$.$2$. Carbylamine test: Lysine $(Lys)$ contains a primary amine $(-NH_2)$ group,which gives a positive carbylamine test. Thus,$B-S$.$3$. Phthalein dye test: Tyrosine $(Tyr)$ contains a phenolic group,which reacts with phthalic anhydride to form a phthalein dye. Thus,$C-P$.Therefore,the correct matching is $A-R, B-S, C-P$.

Item $I$	Item $II$
$A$. Ester test	$P$. Tyr
$B$. Carbylamine test	$Q$. Asp
$C$. Phthalein dye test	$R$. Ser
	$S$. Lys

The correct match between Item $I$ and Item $II$ is

Item $I$ Item $II$

$A$. Ester test $P$. Tyr

$B$. Carbylamine test $Q$. Asp

$C$. Phthalein dye test $R$. Ser

$S$. Lys
