PPT-Protein Tertiary Structure

What to Know What are some protein functions General principles for protein folding General structural features of globular and structural proteins Know the 4 common globular protein motifs Understand how protein structures are stabilized and why some portions of proteins are marginally stable. Why do we want to know protein structure?. Classification. Functional Prediction. What is protein structure?. Primary - chains of amino acids. Secondary - interaction between groups of amino acids. Tertiary - the organization in three dimensions of all the atoms in a polypeptide. and Tertiary . Structure. Need TO Book. Plasticene. OHP, OHT, OHT pens. Textbooks. Repro: . Sources. Flipped learning task (in folder lesson 8) to set as homework. Success Criteria. Know about protein structure. C483 Spring 2013. 1. Which . statement is false about a globular protein that performs its biological function as a single independent polypeptide chain?. A. ) Its tertiary structure is likely stabilized by the interactions of amino acid side chains . General. Amino Acids:. Building blocks for peptides, proteins. Some individually important (or converted to important molecules). Gly. , . Glu. , Tyr .  neurotransmitters. Tyr  . parent/precursor. PROTEIN STRUCTURE. To understand how drugs interact it is necessary to understand their structure.. Proteins have four level of structure:-. PRIMARY . SECONDARY. TERTIARY. QUATERNARY. 1.PRIMARY STRUCTURE:-. The ribbon model represents the tertiary structure of the polypeptide chain that forms myoglobin, a globular protein.. Learning Goal . Describe the tertiary and quaternary structures of a protein..

Denaturation of proteins.. Proteins are biopolymers, made of the 20 L- . α. -amino acids linked by peptide bonds.. Polypeptide backbone is a repeating sequence of. . N-C-C-N-C-C…. The side chain or R group is not a part of the backbone or the peptide bond.. Localized arrangement of adjacent amino acids formed as the polypeptide chain folds.. The regions of ordered structures formed by interaction of hydrogen bond donor and hydrogen bond acceptor residues of the repeating peptide unit. This has proved to be a very challenging problem. It has aptly been described as the second half of the genetic code, and as the three-dimensional code, as opposed to the one-dimensional code involved in nucleotide/amino acid sequence. .
