1.Write the equation that represents the reaction of pyruvic acid in water. (You will find the structure of pyruvic acid in the Common Acids in Biochemistry and Medicinetable. Omit states-of-matter from your answer.)
2.Label the conjugate acid-base pairs. (Omit states-of-matter from your answer. Separate substances in a list with a comma.) Conjugate acid-base pair that includes pyruvic acid:
3.Conjugate acid-base pair that does not include pyruvic acid:
Common Acids in Biochemistry and Medicine Biological Role HCl is the main component of gastric juice, Molecule Structure Hydrochloric acid (HCI) H-Cl found in the stomach. H-O-P-O-H Phosphate esters are derived from Phosphoric acid (H3PO4) phosphoric acid. They are found in ATP, DNA, and RNA. Dissolved carbon dioxide (CO2) reacts with water to produce carbonic acid, a component of the carbonic acid-hydrogen carbonate buffer in the blood and essential for controlling blood pH. Carbonic acid (H2CO3) H-O-C-O-H H O Acetic acid is a key molecule in the Acetic acid (C H,O H-C-C-O-H metabolism of carbohydrates and fats. O H H O Citric acid is formed in the citric acid cycle, a biochemical pathway involved in energy production. Also a common component of fruits and vegetables. Citric acid (CgHgO7) H-O-C-C-C-C-C-O-H H H O Lactic acid is produced in anaerobic l processes, such as during Lactic acid (C3H6O3) intense exercise. Microorganisms also produce lactic acid as a waste product of metabolism. H O Pyruvic acid is produced in the metabolism Pyruvic acid (C3H4O3) H-C-C-C-O-H of glucose. H O The hydrogen atoms highlighted in red can be released as protons, H, in aqueous solution, the acidic hydrogens.
