Consider a small protein containing 101 amino acid residues. The protein would have 100 peptide bonds about which rotation can occur. Assume three orientations are possible about each of these bonds. (a) How many random-coil conformations will be possible for this protein (b) Estimate the conformational entropy change on folding 1 mole of this protein into a native structure with only one conformation (c) If the protein folds entirely into alpha-helix with H-bonds as the only source of enthalpy of stabilization, and each mole of H-bonds contribute -5 kJ/mol to the enthalpy, estimate ΔHfolding. Note that you can not form 4 H-bonds at one end. (d) From (b) and (c), estimate ΔGfolding for this protein at 298 K. Is the folded form stable at 298 K? (biochemistry)

Actual ingredients of lab (the cookies i am actually making) 1/2 cup sugar 1/2 cup brown sugar 1 1/3 stick margarine 1 egg 1/2 tsp salt 1 tsp vanilla 1/2 tsp baking soda 1 1/2 cup flour 1 1/3 cup chocolate chip can you answer the questions below ? discussion 1. suppose you are given the following amounts of ingredients: 1 dozen eggs 24 tsp. of vanilla 1 lb. (82 tsp.) of salt 1 lb. (84 tsp.) of baking soda 3 cups of chocolate chips 5 lb. (11 cups) of sugar 2 lb. (4 cups) of brown sugar 1 lb. (4 sticks) of margarine a. for each ingredient, calculate how many cookies could be prepared if all of that ingredient were consumed. (for example, the recipe shows that using 1 egg- with the right amounts of the other ingredients- yields 24 cookies. how many cookies can you make if the recipe is increased proportionately for 12 eggs? ) b. to determine the limiting reactant for the new ingredients list, identify which ingredient will result in the fewest number of cookies. c. what is the maximum number of cookies that can be produced from the new amounts of ingredients?
