Monosaccharide

Vedclass · Answer

(B) Ninhydrin reacts with amino groups in proteins and amino acids to produce a blue-violet color. Monosaccharides (like glucose) contain a free aldehyde or ketone group,which reduces Benedict's solution (alkaline $CuSO_4$ and citrate ions) to form a red precipitate of $Cu_2O$. Since monosaccharides do not contain free amino groups,they do not react with ninhydrin,making them the correct answer.

Which of the following compounds does not give a test with ninhydrin but gives a positive test with Benedict's solution?
