  • AP Biology Names___Biomolecule Stations Per
    AP Biology Names____________________________________ Biomolecule Stations Per.______________ In this two-day activity, you will move through several different stations and learn about the four macromolecules in the biological world. Day 1: Modeling Carbohydrates and Lipids 1. Use the 3d-printed models to answer the questions for carbohydrates and lipids. NOTE: Blank corners indicate “carbon” atoms. Glucose Fructose Glycerol Acetic Acid Butyric Acid Caproic Acid Day 2: Modeling Proteins 1. Using the Amino Acid Sidechain list, organize the sidechains on the circular magnetic mat according to their name or properties. 2. Examine the side chains and their positions on the circle. Describe your observations on your answer sheet by answering questions #1-6 under Modeling Proteins. 3. Now you have explored the chemical properties and atomic composition of each sidechain, you are ready to predict how proteins spontaneously fold up into their 3D shapes. Answer questions #7-8 on your answer sheet. 4. Unwind the yellow tube. Notice the blue and red end caps. The blue end cap represents the N- terminus (the beginning) and the red end cap represents the C-terminus (the end) of the protein. 5. Select 15 metal U-shaped clips from your kit. Beginning at the N-terminus, place the 15 u-clips three inches apart on the tube. 6. Select methionine from the mat and place it on the clip closest to the blue end cap. Choose six hydrophobic sidechains, two acidic sidechains, two basic sidechains, two cysteine sidechains, and two other polar sidechains. Place them in any order you choose on your tubes u-clips.

Weber, Ph.D. Eddy M. Rojas, Ph.D., M.A., P.E. Associate Dean Dean School of Engineering School of Engineering ii c Copyright by Danielle Nichole Bane All rights reserved 2015 ABSTRACT A RESONANT CAPACITIVE TEST STRUCTURE FOR BIOMOLECULE SENSING Name: Bane, Danielle Nichole University of Dayton Advisors: Dr. Guru Subramanyam and Dr. Karolyn M. Hansen Detection of biomolecules in aqueous or vapor phase is a valuable metric in the assessment of health and human performance. For this purpose, resonant capacitive sensors are designed and fab- ricated. The sensor platform used is a resonant test structure (RTS) with a molecular recognition element (MRE) functionalized guanine dielectric layer used as the sensing layer. The sensors are designed such that the selective binding of the biomarkers of interest with the MREs is expected to cause a shift in the test structure’s resonant frequency, amplitude, and phase thereby indicating the biomarker’s presence. This thesis covers several aspects of the design and development of these biosensors.

  • Metabolic Fate of Glucose Metabolic Fate of Fatty Acids
    CHEM464/Medh, J.D. Integration of Metabolism Metabolic Fate of Glucose • Each class of biomolecule has alternative fates depending on the metabolic state of the body. • Glucose: The intracellular form of glucose is glucose-6- phosphate. • Only liver cells have the enzyme glucose-6-phosphatase that dephosphorylates G-6-P and releases glucose into the blood for use by other tissues • G-6-P can be oxidized for energy in the form of ATP and NADH • G-6-P can be converted to acetyl CoA and then fat. • Excess G-6-P is stored away as glycogen. • G-6-P can be shunted into the pentose phosphate pathway to generate NADPH and ribose-5-phosphate. Metabolic Fate of Fatty Acids • Fatty acids are oxidized to acetyl CoA for energy production in the form of NADH. • Fatty acids can be converted to ketone bodies. KB can be used as fuel in extrahepatic tissues. • Palmityl CoA is a precursor of mono- and poly- unsaturated fatty acids. • Fatty acids are used for the biosynthesis of bioactive molecules such as arachidonic acid and eicosanoids. • Cholesterol, steroids and steroid hormones are all derived from fatty acids. • Excess fatty acids are stored away as triglycerides in adipose tissue. 1 CHEM464/Medh, J.D. Integration of Metabolism Metabolic Fate of Amino Acids • Amino acids are used for the synthesis of enzymes, transporters and other physiologically significant proteins. • Amino acid N is required for synthesis of the cell’s genetic information (synthesis of nitrogenous bases). • Several biologically active molecules such as neuro- transmitters, porphyrins etc. • Amino acids are precursors of several hormones (peptide hormones like insulin and glucagon and Amine hormones such as catecholamines).
