Objective The Biuret test provides a qualitative assessment of protein presence by detecting the peptide bonds between amino acids, which are the building blocks of proteins. The test relies on the reaction between proteins and copper(II) ions under alkaline conditions. In the Biuret test, the sample is mixed with a reagent containing copper(II) sulfate (CuSO4) … Read more
Objective Seliwanoff’s test is a biochemical test devised by the Russian chemist Theodore Seliwanoff in 1887. The main objective of Seliwanoff’s Test is to differentiate between aldoses and ketoses based on their reaction with Seliwanoff’s reagent. Aldoses, which have a terminal aldehyde group, do not give a strong positive reaction or give a much slower … Read more
Objective Barfoed’s test is a biochemical test devised by the Swedish physician C.T Barfoed (1815-1899). The test is a chemical test used to differentiate between monosaccharides (simple sugars) and disaccharides, particularly between monosaccharides containing an aldehyde group and those that do not. The main objective of Barfoed’s test is to distinguish between monosaccharides and certain … Read more
Objective Molisch’s test is a sensitive chemical test, named after Australian Botanist Hans Molisch. It is a chemical test used to detect the presence of carbohydrates, specifically the presence of any form of carbohydrate that can be hydrolyzed to form simple sugars, such as glucose. The objective of Molisch’s test is to identify the presence … Read more
Principle Of Iodine Test For Starch The starch-iodide complex as charge is transferred between the starch and iodide ions (tri-iodide or pentaiodide). The transfer of the charge between the starch and the iodide ion changes the spacing between energy levels/orbitals. This change results in the starch-iodide complex absorbing light at different wavelength resulting in an … Read more
Anglicanism and Catholicism are two prominent religion, each weaving its own rich narrative of faith, tradition and theological conviction. More generally they can be called Anglicanism and Catholicism. The word Catholic comes from the Greek word “katholikos” which means Universal. It’s the first form of Christianity, which was originated when Christ apostles started preaching after … Read more
In statistics and data analysis, understanding numeric concepts is very important. Most of the time, terms that appear similar can have different meanings and result to misinterpretations and erroneous conclusions. This is especially true when dealing with the concepts of percentage and percentile in diverse fields like education, finance or healthcare and research. Let us … Read more
Sunni and Shia are the two main sub-groups of Islam. Sunni and Shia share the most of the fundamental Islamic beliefs and articles of faith. The emergence of these two sub-groups can be traced way back to 623 A.D, when the Islamic Prophet Muhammad died. The death of Prophet Muhammad occasioned a debate as to … Read more
What Is A Conductor? In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electricity) through them. Conductors have free electrons on its surface which allows current to pass through. This is the reason why they are able to conduct electricity. Conductors also have can … Read more
