- d-Glucuronic acid is found widely in plants and animals. One of its functions is to detoxify poisonous HO-containing compoundsby reacting with them in the liver to form glucuronides. Glucuronides are water soluble and therefore readily excreted. Afteringestion of a poison such as turpentine or phenol, the glucuronides of these compounds are found in the urine. Draw thestructure of the a- and b-glucuronides formed by the reaction of b-d-glucuronic acid and phenol.rivatives: Nucleophilic Acyl Substitution Reactions - EOC O C-O [References] One step in the gluconeogenesis pathway for the biosynthesis of glucose is the partial reduction of 3-phosphoglycerate to give glyceraldehyde 3-phosphate. The process occurs by phosphorylation with ATP to give 1,3-bisphosphoglycerate, reaction with a thiol group on the enzyme to give an enzyme-bound thioester, and reduction with NADH.

Propose a mechanism, using acid or base catalysis as needed.
- Following are the steps in the industrial synthesis of glycerin. Provide structures for all intermediate compounds (AD) and describe the type of mechanism by which each is formed.The formation of Br2 from NBS first involves the reaction of NBS with HBr to form an iminol intermediate and molecular bromine. The intermediate then undergoes acid-catalyzed tautomerism to form succinimide, the byproduct of the reaction. Propose a curved-arrow mechanism for the conversion of NBS into succinimide that also accounts for the formation of Br2.If a solution of compound X is ncubated with a catalytic anount of enzyme Y the sucrose is trarsformed to glucose aid Euctose in the reaction 1X 1 fedose3 ghacose A eqahum, The concenttons of the seation comgoests he and 2mM glucose.

- 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 OR-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 can you 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?22,23The dynamic process by which both forms of a- and B-D-glucopyranose in solution change slowly into an equilibrium mixture of both is known as (choose the name).
