The test relies on the dehydration of carbohydrates by a strong mineral acid.

The chemical principle behind this elegant reaction is a two-step process. Initially, the strong, concentrated acid causes the carbohydrate molecule to undergo dehydration, effectively removing water molecules. This process converts pentose sugars (five-carbon sugars) into a compound called furfural and hexose sugars (six-carbon sugars) into a derivative known as 5-hydroxymethylfurfural. In the second step, these newly formed aldehyde compounds react with the α-naphthol present in the Molisch reagent, leading to a condensation reaction that produces the characteristic purple-colored product. A key advantage of the Molisch test is its inclusivity: it yields positive results for virtually all types of carbohydrates, including monosaccharides (like glucose and fructose), disaccharides (such as sucrose and lactose), and polysaccharides (like starch and glycogen). However, this "universal" nature is also its main limitation, as it cannot differentiate between these different types of carbohydrates.
: Because it reacts with nearly all carbohydrates, it is used as a preliminary "screening" test to confirm if a substance contains any sugar at all, rather than identifying a specific type of sugar. Interpretasi Hasil dan Pembahasan Hasil Positif The test
