The KSP for BaCO3 is 5.1X10-9. How many grams of BaCO3 will dissolve in 1000mL of water?

1. Penicillin is hydrolyzed and thereby rendered inactive penicillinase, an enzyme present in some penicillin-resistant bacteria. The molecular weight of this enzyme in Staphylococcus aureus is 29.6 kilo Daltons (29.6 kg/mole or 29,600 g/mole or 29,600 ng/nmole) The amount of penicillin hydrolyzed in 2 minute in a 10-mL solution containing 109 g (1 ng) of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change appreciably during the assay. [Hint: Convert everything to the same concentration terms] Show all calculations and include spreadsheets and graphs to determine Km, Vmax and kcat for this enzyme. Make sure your final answers have correct units. [Another hint: Note that [S] and amount hydrolyzed are already in concentration terms. So you don't need to worry about the volume for calculating [S] and V. ] Penicillin concentration (microM) Amount hydrolyzed (nanoM) 1 110 3 250 5 340 10 450 30 580…

1. A daily low dosage of aspirin (acetylsalicylic acid) can lower the risk of heart attack and stroke for individuals at risk. Aspirin suppresses the generation of prostaglandins by irreversible binding to the enzyme COX-1. Inhibition of prostaglandin synthesis lowers the production of thromboxanes that are responsible for the aggregation of platelets and the formation of blood clots. You will explore the mechanism of aspirin binding. 1.1 The average pH of the human body is 7.4 (also known as a physiological pH). Draw the structure of aspirin at a physiological pH. OH 1.2 Aspirin reacts with the amino acid Serine. What is the structure of serine? Draw the structure of the tripeptide Ala-Ser-Trp (draw these structures as they exist at physiological pH) serine Ala-Ser-Trp 1.3 Aspirin reacts with Serine 530 of COX-1 by transesterification reaction. Draw a general mechanism of acid-catalyzed transesterification reaction. Use HA as an acid. 1.4 Draw an arrow-pushing mechanism for the…

I ces 5. Assign a systemic name for the following compounds. る

Of the choices, could you please advise which would be best?

noradrenaline and serotonin in the spinal cord. Deduce the structure of this new compound, given its molecular neuron to another. Noradrenaline (also called norepinephrine) and serotonin are neurotransmitters that act in its) Neurotransmitters are small molecules that are produced by the body to send messages from one the central nervous system. A recently report synthetic compound has effects that are similar to baul formula (CəH13NO) and the following 'H NMR spectral data. Show your work by labeling your proposed structure with the corresponding letters for the signals listed below. a) 1.1 6 (2H, broad singlet) b) 2.7 6 (2H, triplet) c) 2.9 6 (2H, triplet) d) 3.8 6 (3H, singlet) e) 6.8 6 (2H, doublet) f) 7.1 6 (2H, doublet)
