The classification system for monosaccharides is similar to the IUPAC naming system chain length and carbonyl group of simple sugars." a) Indicate the two structural features specified by the "aldotriose classification b) Now draw the structure of an "aldotriose.“ 2. or the carbohydrate diagnostic tests, the Benedict's Test for reducing gars" is perhaps the most significant, as it was once the standard test for...
please help me type my introduction for my lab report. thank you!! INTRODUCTION In this section, you will introduce the experiment by explaining generally what you did and why you did it. This section usually starts with an examination of the literature through a library search to inform the reader about work already done on this topic. If you have never done a bibliographic database search for scientific journal articles, then you are not yet a biological sciences major (note:...
Post Lab Questions: 1. Two molecules of glucose, a monosaccharide, when joined together they form a molecule of maltose. Write a chemical reaction to show this process. 2. Write the chemical reaction to show the charring of glucose, C.H.O., which occurs on addition of Conc. H SO. to it. 3. What is the role of Conc. H2SO. in Molisch's reagent test? 4. The positive Biuret test indicates the presence of ....... bond in proteins. 5. Why would amino acids give...
