Xanthoproteic Test for Aromatic Amino Acids

The xanthoproteic test is a chemical test that is used to identify the presence of certain amino acids in a sample. The test involves the us...

Solubility Tests for Amino Acids and Proteins

The solubility of amino acids and proteins is largely dependent on the pH of the solution. The structural changes that occur at different pH...

Osazone Test or Phenylhydrazine Test

This test is used to distinguish between lactose and maltose. The organic compound phenylhydrazine reacts to form osazones with the carbonyl...

Mucic Acid Test for Galactose

This test is highly specific to galactose, which is either present in solutions independently or obtained by lactose hydrolysis. On heating ...

Bial's Test for Pentoses

This test is specific to pentoses and to pentose-containing compounds and is therefore useful for pentose sugar determination. The reaction ...

Seliwanoff’s Test for the Differentiation of Aldoses from Ketoses

This test is a keto hexose-specific timed colour reaction. It is therefore used for the differentiation of aldoses from ketoses. Dehydration...

Picric Acid Test for Sugar Reduction Detection

This is another test for sugar reduction detection. To form a red colored Picramic Acid, the decreasing sugars react with Picric Acid. Reage...
