PPT-Protein Structure of Protein

Contains carbon hydrogen oxygen and nitrogen Remember carbohydrates and lipids contain carbon hydrogen and oxygen SO protein adds nitrogen Some proteins also contain sulfur iron copper phosphorus or . 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. SUMI SINGH. (sxs5729). Levels of Protein Structure. 2. Thanks to: Frank . Lloyd . Wright for graphics.
