Glycine

Vedclass · Answer

(D) The general formula for an amino acid is $NH_2-CH(R)-COOH$. The molecular mass depends on the side chain $R$. For $Glycine$,$R = H$ (molecular formula $C_2H_5NO_2$,molar mass $\approx 75 \ g/mol$). For $Serine$,$R = CH_2OH$. For $Aspartic \ acid$,$R = CH_2COOH$. For $Proline$,it is a cyclic amino acid with a larger structure. Since $Glycine$ has the simplest side chain $(H)$,it has the lowest molecular mass among the given options. Therefore,the correct option is $D$.

$A$. Arginine	$I$. $D$
$B$. Aspartic acid	$II$. $N$
$C$. Asparagine	$III$. $A$
$D$. Alanine	$IV$. $R$
