Enzyme b. Binding: Electrostatic Forces Substrates bind to receptors and enzymes through non-covalent interactions (intermolecular forces – IMF). Below is a cartoon of a part of a ligand or substrate interacting with an enzyme (blue line). There are two aspartic acid side chains of the enzyme that are interacting with the substrate (dashed lines). Identify the intermolecular forces. OH R Asp 125 -4----* H-o Asp25 Enzyme Active Site

a) Lysine is an essential amino acid. It is taken by some people as a nutritional supplement in the form of a hydrated crystalline solid with the formula C6H₁4N2O2.XH₂O . To control the dose of lysine, it is essential to know the complete formula of the hydrate, which means determining the value of x. To determine the value of x in lysine hydrate, a pharmacist used a direct titration method. She dissolved 6.258g of the compound in approximately 100mL of distilled water and then made this up to 250mL in a volumetric flask. She then titrated 25mL aliquots of this solution with a standardized NaOH solution of concentration 0.1050 mol dm-³, obtaining a mean titre of 36.30 mL. In titrations, lysine behaves as a monoprotic acid. Use these data to determine the value of x in lysine hydrate. b) In a second experiment to verify the value of x, the pharmacist heated a 3.752g sample of the lysine hydrate to drive off all the water. When she reweighed the sample, the mass was 3.278 g. Use this…

One of the most common types of kidney stones are composed of calcium oxalate. In addition to calcium oxalate another product is also formed in the formation of kidney stones in the body. Certain foods are high in oxalate and lead to an increase of forming kidney stones in the human body. These high-risk foods are as follows:   Spinach Swiss Chard Almonds (nuts in general) Sesame Seeds Soy Products (such as soy-based milk, cheese, yogurt) Sweet Potatoes Okra Beets Chocolate Black Tea   Another risk factor to developing kidney stones is not drinking enough water. Males have a higher chance than females of developing kidney stones, with the average age being 30. Oxalate in food binds to calcium during digestion in the stomach and intestines and then is excreted in the body as waste. If too much oxalate appears in the urine and not enough liquid (due to not drinking enough water), then calcium oxalate crystals form, which are the kidney stone.  A 35 year old male was taken to the hospital…

Select either atom that forms the glycosidic bond in this molecule, sucrose. Gray = C; white = H; red = 0; blue = N; dark green = Cl; brown = Br; light green = F; purple = I; yellow = S; orange = P. • Double click to select atoms. • You can zoom in and out using the mouse scroll wheel (or pinch to zoom on touch screens). • If there is more than 1 correct answer, just give one.

Calculate the number of joules in Product A, and enter your answer in Canvas. Show all work on your scratch paper. Fat (g) Carbohydrates (g) Protein (g) Product A 12.1 25.2 4.9 Product B 4.0 25.4 5.4 Once you are finished with Product A, ON YOUR SCRATCH PAPER calculate the total joules contained in product B, and clearly indicate which has more calories.

Draw the organic product(s) for each of the following reactions. If more than one product is expected indicate the major product.

The acid-catalyzed hydrolysis of sucrose, C12H22O11 + H₂O + H+ -> C6H12O6 + C6H12O6 + H+ is known as "inversion of sucrose" because the angle, a, by which the solution rotates polarized light changes from positive to negative as the reaction proceeds (data from 30 degree C): t/hr a 0 78 2 71 4 12 18 24 42 65.10 44.60 32.40 22.45 2.30 48 -1.96 61 -9 86 95 -15.80 -17.25 -21.15 ∞ Use this data to show that the reaction is first order and determine its rate coefficient (at 30 degree C).

A research group discovers a neW version oI happyasee, which they nappyase", that catalyzes the chemical reaction HAPPY = SAD The researchers begin to characterize the enzyme. In the first experiment, with [E] at 4 nM, they find that the Vmax is 1.6 µM s-1. Based on this experiment, what is the kcat for happyase*? kcat 400 S In another experiment, with [E,] at 1 nM and [HAPPY] at 30 µM, the researchers find that Vo is equal to 300 nM s-1. What i the measured Km of happyase* for its substrate HAPPY? Km 10 x10–6 Incorrect Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase* preparation, and the two experiments repeated, the measured Vmax increases to 4.8 µM s-, and the measured Km is now 15 µM. S For the inhibitor ANGER, calculate the values of a' and a. a' 2 Incorrect 2
