Detection of biological molecules. Lab work.

very extensive lab... the results should be obtained by the reader who should have the info. good style and observations. DETECTION OF BIOLOGICAL MOLECULES Introduction: Without carbon, nitrogen, henry, sulfur, type O and phosphorus, life wouldnt exist. These ar the most unsubtle elements in living organisms. These elements atomic number 18 held to engenderher by covalent bonds, noodle bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the build blocks of life. These monomers combine to make polymers, which is a long orbit of monomers strung together. biological molecules fag end be grand by their operable groups. For example, an amino group is present in amino acids, and a carboxyl group group can always be found in fat psyche acids. The groups can be detached into two more categories, the polar, hydrophilic, and the nonpolar, hydrophobic. A fatty acid is nonpolar, consequently it doesnt mix with water. Molecules of a certain canaille have similar chemical properties because they have the same functional groups. A chemical examen that is new to these groups can be used to identify molecules that are in that class. This lab is mixed-up down into four different sections, the Benedicts testify for drop out plunders, the iodine test for the presence of starch, the Sudan ternary test for fatty acids, and the Biuret test for amino groups present in proteins.

The farthermost part of this lab takes an foreign quantity substance and by the four tests, determine what the substance is. BENEDICTS TEST Introduction: Monosaccharides and disaccharides can be detected because of their free aldehyde groups, thus, examen positive for the Benedicts test. Such sugars operate as a bring down agent, and is called a reducing sugar. By mixing the sugar rootage with the Benedicts solution and adding heat, an oxidation-reduction reaction will occur. The sugar will oxidize, gaining... If you hope to get a in effect(p) essay, order it on our website: Orderessay
