PPT-Lecture 2. Protein structure: primary, secondary, tertiary and quaternary structure.

Proteins are biopolymers made of the 20 L α amino acids linked by peptide bonds Polypeptide backbone is a repeating sequence of NCCNCC The side chain or R group is not a part of the backbone or the peptide bond. 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. Ch. . 9 Part 1. Warm Up. The idea that once a culture locates in another area, the original customs and traditions eventually die out or are less strong is:. Place utility. Acculturation. Distance decay. 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.. Tertiary Structure. The ribbon model represents the tertiary structure of the polypeptide chain that forms myoglobin, a globular protein.. Learning Goal .
