Biochemistry I Exam 3 Review Sheet Protein Chemistry Identify chiral carbons Identify amino acids (AA) as D or L Identify the 20 AA List the 9 essential AA List ketogenic AA, both ketogenic & glucogenic AA & only glucogenic AA List polar, nonpolar, & aromatic AA List 3 branched chain AA. Where are they metabolized? Which AA is a precursor to cholesterol? Serotonin? Dopamine? Thyroxine? Which AA is replaced in sickle cell anemia? Which cofactor(s) are necessary for AA metabolism? Which coenzyme(s)? List complete & incomplete proteins (which AA is/are missing in corn, wheat, rice, and legumes?) Where does most of our protein in our AA pool come from? What are some causes of recycling? Compare positive & negative nitrogen balance Be able to determine which protonated/deprotonated AA structures will be found at a given pH (pKs will be given)

    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.
