Select the correct statement among the following
1 Alanine is an acidic aminoacid
2 Ketohexose (fructose) does not change the colour of \(\mathrm{\mathrm{Br}_{2}}\) water
3 Uracil is N -base of DNA
4 D- glucose and D - fructose form different osazone with excess of \(\mathrm{\mathrm{H}_{2} \mathrm{NNHPh}}\)
Explanation:
Due to less reactive towards to oxidation by ketohexose.
