1 LECTURE 6: PROTEINS Protein Outline 2 Proteins (structure and function) ?Major roles in physiology & structural frameworks ?Amino acid structure ?Levels of structural organization: (primary, secondary, tertiary, quaternary) ?Properties (relate to structure) ? Major classes of proteins Objectives 3 1. Describe the structure of amino acids 2. Outline how proteins are formed by peptide bonds. 3. Describe how proteins are organized at the primary, secondary, tertiary, quaternary levels. 4. State the functions of proteins 5. Classify proteins according to structure/solubility, composition, function. Proteins 4 ?More than 50% of the dry mass of an organism consists of proteins.

Knowledge gained through careful observation, experimentation and reasoning. ? Science is: ? Explanatory ? Testable ? Reproducible ? Predictive ? Tentative Questions of Science Scientific discoveries create complex questions: ? Ex. Atom ? Should scientists be free to pursue any research? ? Cloning/Stem cell. ? Should government control scientific progress? ? Progression of science. ? Research normally follows a logical progression. ? Interest focuses on problems that impact humanity. The Importance of Publication ? Results of research are submitted for publication. ? peer review by other

Fenn, Koichi Tanaka, Kurt W?thrich ( nglish Swedish Popular Information Information for tK H PuEliF 9 October 2002 The Nobel Prize in Chemistry for 2002 is being shared between scientists in two important fields: mass spectrometry (MS) and nuclear magnetic resonance (NMR). The Laureates, John B. Fenn and Koichi Tanaka (for MS) and Kurt W?thrich (for NMR), have contributed in different ways to the further development of these methods to embrace biological macromolecules. This has meant a revolutionary breakthrough, making

Macromolecules Macromolecules The topic of macromolecules lends itself well to illustrate three integral themes woven throughout the text and course: There is a natural hierarchy of structural level in biological organization As one moves up the hierarchy, new properties emerge because of interactions among subunits at the lower levels Form fits function. Most macromolecules are polymers Polymer = (Poly = many; mer = part) Large molecule consisting of many identical or similar subunits connected together. Monomer = Subunit or building block molecule of a polymer. Macromolecule = (Macro large) Large organic polymer. Formation of macromolecules from smaller building block molecules represents another level in the hierarchy of biological organization.
