Identification of Macromolecules- Lab Report Essays

Identification of Macromolecules- Lab Report Essays Identification of Macromolecules- Lab Report Paper Identification of Macromolecules- Lab Report Paper I no color change I I Red light blue Proteins are the basis of the protoplasm (fluid living content of the cell that contains the cytoplasm and cell nucleus) and are found in all living organisms. Proteins make up the bulk of animals bodys non-skeletal structure. As enzymes, they catalyst biochemical reactions; as antibodies, they prevent the effects of invading organisms; and as hormones, they control metabolic processes (C. Bassoonists, 2011). The Beirut test was used to detect the presence of peptide bonds within proteins, and they were found present in test tube #9 (control for peptide bonds). Reducing sugars are inconsiderate that have equilibrium with the straight-chain and cyclic form, which the sugar engages in an oxidation- reduction reaction with Cue+ (C. Bassoonists, 2011). Through this test, one is able to determine that the unknown solution #128 is a non-reducing sugar because the results show that the test turned out positive, and reducing sugars cause The iodine test is used to identify glycogen and starch. Negative tests to occur. These polysaccharides combine with iodine to form either a blue/black color for the presence of starch) or a red/brown color (for the presence of glycogen) (Chemo, 2003). Polysaccharides are a formation of macroeconomicss linked together. The simplest polysaccharides contain two sugars and are given the name disaccharide. Starch is a storage polysaccharide in plants where as glycogen is a highly branched storage polysaccharide in animals. Both play a part in providing energy. The glucose produced in plants are stored in the form of starch and then released when energy is needed. Glycogen is stored in the liver and muscles of animals, and is released when energy is needed with the help of enzymes breaking down the glycogen (J. Sharp, 2011 Starch was present in test tube #8 (control for starch) and glycogen was present in test tube #7 (control for glycogen). The results that one obtains from this experiment closely match the results of other groups when compared during lab. This experiment gave an understanding of the different types of color change reaction that occurred when each solution reacted with the testing solutions. Also, with the aid of the results from the sample solutions, one is able to compare and determine what the unknown solution was as well.
