discussion abut bial test ??
Bials orcinol is a reagent used to colorimetrically determine the presence of ribose sugar in nucleic acids. It reacts with the ribose sugar to form a colored complex, allowing for the quantification of RNA or DNA in a sample.
Glucose, fructose, maltose, sucrose, lactose, and starch are carbohydrates that would likely test positive in Molisch, Benedict's, Barfoed's, Seliwanoff's, Bial's, and fermentation tests. These carbohydrates are commonly used in biochemical testing due to their distinct reactivity with the specific reagents in each test.
The Biuret test detects the presence of peptide bonds in a protein. The chemical equation for the Biuret test involves the reaction of Cu2+ ions with peptide bonds, forming a violet-colored complex. The equation can be represented as: Cu2+ + peptide bond → purple complex
