What is the Molisch test for carbohydrates?
Molisch's test is based on the dehydration of sulphuric acid into furfural. One hydroxyl group is removed from a sugar molecule when a sample containing carbohydrate molecules is treated with sulphuric acid and concentrated hydrochloric acid. Water is used to eliminate the hydroxyl group.- Molisch's Test is a sensitive chemical test for all carbohydrates, and some compounds containing carbohydrates in a combined form, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde (either furfural or a derivative), which then condenses with the phenolic structure resulting in a red
