Chem-102 Lab Dr. Sobhi Experiment #3: Spectrophotometric Determination of Tartrazine Purpose The objectives of this lab include- illustrating the use of the spectrophotometer in chemical analysis‚ and generating a standard‚ or calibration curve‚ then using that curve to determine the value of an unknown substance. The spectrophotometer is one of the most powerful tools used in chemistry to find the concentration of substances in solution. It compares the colors of a known and an unknown solution

glucose solution‚ sucrose solution‚ starch solution and distilled water were added separately into six marked test tubes. The volume added was about one finger thick in depth of a test tube. 2. 5 drops of Iodine solution was added to each test tube. 3. The sample’s reaction with iodine was recorded. 4. The samples connected by another group with 5 drops of Benedict’s solution added were heated all together in hot water bath. 5. The test tubes containing samples were taken out of the hot water bath

The Different Roles of Macromolecules in Biology.There are four types of macromolecules that I am going to describe: Proteins‚ carbohydrates‚ lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide)

Interpretation of Results As observed by the group in a normal diode circuit placed in a forward bias generates a sinusoidal output wave. In order to trim the output waves‚ that are a sinusoidal wave‚ to be generated‚ a clipper circuit was made with the use of diodes. The limiting level of a clipper circuit is the barrier potential of the diode in use. A diode clipper that trims down the positive half cycle input of a wave signal is as positive limiter. The output signal will retain the original

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. These macromolecules are polar because they are formed by head to tail condensation of polar monomers. Making Glucose: Green plants manufacture glucose through a process that requires light‚ known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence
