Quiz Coverage

Note: Structures are graded all-or-none; be sure to include the appropriate number of hydrogens! If bond structures are drawn, either all or no hydrogens must be shown.

Amino acids quiz (10 pts): Know the structures and abbreviations (both 3-letter and 1-letter) of the 20 principal amino acids; you will be asked to draw two structures and give the abbreviations. (Note: for the ionizable R-groups, draw the form that predominates at pH 7.)

Carbohydrates quiz (10 pts): Know:

You will be asked to draw two of these structures.

Fatty acids quiz (10 pts): Know the structures of and be able to write the symbols for:

You will be asked to draw two structures and give their omega or delta symbol. (Note: draw the form that predominates at pH 7.)

Glycolysis quiz (10 pts): Know the names and structures (Haworth or Fisher projection) of all pathway intermediates; you will be asked to write all names and draw one structure.

Cofactors quiz (10 pts): Be familiar with the structures and properties of ATP, ADP, AMP, NAD, NADP, FAD, FMN, biotin, TPP, lipoate, coenzyme A, coenzyme Q, and heme. You will be provided two structures, and for each you will be asked to: (1) give the abbreviation (with correct redox state, if applicable); (2) circle the reactive portion; (3) answer whether it is a prosthetic group and whether it is a redox cofactor.

TCA cycle quiz (10 pts): Know the names and structures of all intermediates, and know the side reactants & products (like ATP, GTP, NADH, H2O, etc) and their stoichiometries. You will be asked to write all names and side products and draw one structure.
