Lecture 4, January 11 59-63; 78-81 Learning Outcomes 1. List the four levels of protein structure and identify the types of bonds responsible for each. Notebook. 2. Contrast the H-bonding that is responsible for secondary structure to that seen in tertiary structure. Notebook. Secondary- peptide bonds Tertiary- R-groups 3. Identify ways that each type of association seen in tertiary structure can be dissociated. H-bonds-Heat Ionic bonds- change pH, Add salt Hydrophobic- organic solvent (detergent) 4. Explain what is meant by a protein domain. Domains- distinct regions of a protein that fold independentyly of one another generyally

Explain the potential value of molecular chaperones for survival of a cell in heat shock. Molecular chaperones provide proteins the correct folding pathways during heat shock. Hsp60 and Hsp 70. GroEL and GroES are proteins. 6. Draw the structure of GroEL and explain its function. GroEL is a hydrophobic chamber. Facilitate protein folding using ATP ....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
