At the completion of this laboratory, you should be able to: Identify a positive control test reaction for each macromolecule. Use the results of the known test reactions to identify macromolecules. Use the results of the known test reactions to identify macromolecules in unknowns.
Order now 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.
As enzymes, they catalyst biochemical reactions; as antibodies, they prevent the effects of invading organisms; and as hormones, they control metabolic processes C. 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.
Through this test, one is able to determine that the unknown solution 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. 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, 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.Macromolecule Report Monomer units of biological macromolecules have heads and tails.
When they polymerize in a head-to-tail fashion, the resulting polymers also have heads and tails. When they polymerize in a head-to-tail fashion, the resulting polymers also have heads and tails.

Macromolecules: Experiments with Protein. Macromolecules are formed by connecting many smaller molecules together.
The individual components of a macromolecule are referred to as monomers. Proteins are composed of monomers called amino acids.
All amino acids have a carboxyl group, an amino group, and a central or alpha carbon. The central. Macromolecule Lab Answers. Centrifugation of fresh milk and Acetic Acid.
