One can identify phenylketonurics and PKU carriers (heterozygotes) by means of a phenylalanine tolerance test. One injects a large dose of phenylalanine into the bloodstream and measures its clearance from the blood by measuring serum phenylalanine levels at regular intervals. Sketch curves showing relative blood phenylalanine concentration versus time that you would expect to be displayed by (a) a PKU patient, (b) a heterozygote, and (c) a normal individual. What kind of tolerance test could you devise to distinguish between PKU resulting from either phenylalanine hydroxylase deficiency or dihydropteridine reductase deficiency?
1.Why do you think glutathione occurs in a concentration as high as glucose? 2.Explain why glutathione must be transported from cytosol to mitochondria. 3.Explain why glutathione can confer therapeutic benefit when taken orally.
1. Acid phosphatases are an important group of enzymes that can be detected in human bloodserum. Under slightly acidic conditions (pH 5.0), this group of enzymes can hydrolyzebiological phosphate esters as follows:R-O-P-O3-2 + H 2O R-OH + HO-P-O3-2.Acid phosphatases are produced and can be detected in erythrocytes, kidney, spleen, the liver,and prostrate gland. The enzyme from the prostrate gland is clinically important because anincreased activity in the blood is frequently an indication of cancer of the prostrate gland.Tartrate ion can strongly inhibit the phosphatase from the prostrate gland, but not acidphosphatases from other tissues. How can you use the information above to develop a specificprocedure for measuring the activity of the acid phosphatase of the prostrate gland in humanblood serum?

what possible outcome may be produced when the molecular weight of an alcohol antiseptic is increase to a C20, will it still be effective? Explain your answer
Which of the following is a true statement regarding sphingolipid synthesis? (A) The first step in sphingolipid synthesis is the condensation of palmitoyl CoA with aspartate to form b-ketosphinganine.(B) This process requires the reduction of a ketone that uses NADH as the reducing agent.(C) A fatty acid is attached to dihydrosphingosine to form dihydroceramide. (D) FAD is using as an oxidizing agent to remove a double bond from dihydroceramide.(E) The formation of sphingomyelin requires the attachment of a glucose or galactose molecule to ceramide.
The fosfomycin disc (200/50) also contains glucose-6-phosphate (G-6-P). Which ONE of the following best describes why this is the case? Select one: A. G-6-P increases the solubility of fosfomycin B. G-6-P is used to promote active transport of fosfomycin into the bacterial cell C. G-6-P is used in the formulation to correct glucose deficiencies promoted by fosfomycin D. G-6-P stabilises fosfomycin from spontaneous hydrolysis in aqueous solution E. G-6-P is an inhibitor of FosA that inactivates fosfomycin

Decreased negative charges needed at the dimer/dimer interface to stabilize the T-state c. Decreased positive charges needed at the dimer/dimer interface to stabilize the T-state d.

1. Acid phosphatases are an important group of enzymes that can be detected in human blood serum.Under slightly acidic conditions (pH 5.0), this group of enzymes can hydrolyze biological phosphate esters as follows: R-O-P-O3-2 + H 2O  R-OH + HO-P-O3-2. Acid phosphatases are produced and can be detected in erythrocytes, kidney, spleen, the liver, and prostate gland. The enzyme from the prostate gland is clinically important because an increased activity in the blood is frequently an indication of cancer of the prostate gland. Tartrate ion can strongly inhibit the phosphatase from the prostate gland, but not acid phosphatases from other tissues. How canyou use the information above to develop a specific procedure for measuring the activity of the acid phosphatase of the prostate gland in human blood serum?
