Xanthoproteic Test: Objective, Principle, Reagents, Procedure And Result Interpretation

What Is Xanthoproteic test? Xanthoproteic test is a biochemical test for the detection of amino acids having benzene ring in them like phenylalanine, tyrosine and tryptophan (aromatic amino acids). In the Xanthoproteic reaction, the yellowish substance produced by heating protein with nitric acid is xanthoprotein, hence the name Xanthoproteic test.  The test is a qualitative … Read more Xanthoproteic Test: Objective, Principle, Reagents, Procedure And Result Interpretation

Five Different Types of Abiotic Factors

Abiotic factors refer to non-living physical and chemical elements in the ecosystem that affect living organisms in terms of growth, maintenance, reproduction and distribution. They’re at times called abiotic components. Abiotic factors can be classified into five main types namely: climatic factors, topographical factors, edaphic factors, air and chemical elements. All these factors are discussed … Read more Five Different Types of Abiotic Factors
