* Proteins * Understand: * Structure & function of proteins * Amino acid structure & properties * Stages involved with formation of proteins * Primary, secondary, tertiary & quaternary structures * Be able to: * Draw monomer & polymers of proteins * * *Structural support – cytoskeleton, connective tissue *Transport of substances – ion channels (Na+,K+) *Cell signaling – insulin, antibodies *Movement – b/n cells, protein channels *Coordination & regulation of activities – Via shape changes *Accelerating chemical reactions enzymes * *Polymers built from chains of amino acids (polypeptides). * Condensation Reaction * *What do I draw? * * * 1. 2. 3. 4. 5. What 2 functional groups do all amino acids have in common? Write an equation showing the formation of a peptide bond between serine and aspartic acid. Define primary structure and describe how it is specified by genetics. Name the 2 types of secondary structure. What type of intermolecular bond stabilizes secondary structure?
