Detection of biological molecules. Lab work.

very extensive lab... the results should be obtained by the reader who should construct the info. equitable style and observations. DETECTION OF BIOLOGICAL MOLECULES Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldnt exist. These ar the most broad elements in backing organisms. These elements are held to engenderher by covalent bonds, noodle bonds, hydrogen bonds, and disulfide bonds. covalent bonds are especially strong, thus, are indicate in monomers, the build blocks of life. These monomers combine to make polymers, which is a long orbit of monomers set up together. Biological molecules can be distinguished by their operable groups. For example, an amino group is present in amino acids, and a carboxyl group can always be frame in fat person acids. The groups can be disconnected into two more categories, the polar, hydrophilic, and the nonpolar, hydrophobic. A fatty acid is nonpolar , thusly it doesnt mix with water. Molecules of a certain mob have kindred chemical properties because they have the same functional groups. A chemical examen that is sensitive to these groups can be used to mark molecules that are in that class. This lab is broken down into quaternity different sections, the Benedicts test for step-down sugars, the iodine test for the movement of starch, the Sudan III test for fatty acids, and the Biuret test for amino groups present in proteins.

The last part of this lab takes an unknown cadence substance and by the four tests, determine what the substance is. BENEDICTS probe ! Introduction: Monosaccharides and disaccharides can be detected because of their free aldehyde groups, thus, testing positive for the Benedicts test. Such sugars act as a cut back agent, and is called a reducing sugar. By mixing the sugar author with the Benedicts solution and adding heat, an oxidation-reduction reaction testament occur. The sugar will oxidize, gaining... If you want to get a full essay, order it on our website: OrderCustomPaper.com
