Acid-catalyzed Hydrolysis In an acid process the slurry containing about 35–45 starch solids is pumped into a pressure vessel called a ‘converter’ and acidi?ed to a pH of about 2 0 with dilute hydrochloric acid at 140–160°C and a pressure of 80 psi (5 4 atm)
Hydrolysis of Sucrose (Acid versus Base) 1 Place 3 mL of 2 sucrose solution in each of two labeled test tubes To the first test tube (#1) add 3 mL of water and 3 drops of dilute sulfuric acid solution (3 M H 2 SO 4 To the second test tube (#2) add 3 mL of water and 3 drops of dilute sodium hydroxide solution (3 M NaOH)
High fructose corn syrup (HFCS) is a liquid alternative sweetener to sucrose that is made from corn the “king of crops” using chemicals (caustic soda hydrochloric acid) and enzymes (-amylase and glucoamylase) to hydrolyze corn starch to corn syrup containing mostly glucose and a third enzyme (glucose isomerase) to isomerize glucose in corn
Hydrolysis of sucrose: At pH 4 6 sucrose is hydrolysed by ?-fructosidase to D-glucose and D-fructose (?-fructosidase) (5) Sucrose + H2O D-glucose + D-fructose The D-glucose in the sample following hydrolysis of sucrose (total D-glucose) is determined as described above
Fructose 16-bisphosphate Dihydroxyacetone phosphate + Glyceraldehyde 3-phosphate Aldolase We used 2 ATP to generate fructose-16-bisphosphate The six-carbon sugar molecule is split in the middle producing two three-carbon molecules Note: C-C bond cleavage is rare in biochemistry Mechanism
hydroxyl group on C1 forming fructose-16- bisphosphate • Enzyme: phosphofructokinase This allosteric enzyme regulates the pace of glycolysis • Reaction is coupled to the hydrolysis of an ATP to ADP and Pi • This is the second irreversible reaction of the glycolytic pathway • Reaction 4: fructose-16-bisphosphate is split into 2 3
What is the hydrolysis of sucrose and amylose?
The hydrolysis of sucrose or amylose can be achieved by using a strong acid such as HCl or with the aid of biological catalysts (i.e., enzymes). Starch can form an intense, brilliant, dark blue or violet colored complex with iodine.
Does hydrolyzed sucrose give a positive test with Benedict's reagent?
Hydrolyzed sucrose (a mixture of D–glucose and D–fructose) will give a positive test with Benedict’s or Fehling’s reagent as well as hydrolyzed amylose (a mixture of glucose and glucose–containing oligosaccharides).
What is the role of fluoride in glycolysis?
Fluoride inhibition. Fluoride is a classic inhibitor of glycolysis (discovered by Otto Warburg in 1941). It modifies the phosphate and magnesium in enolase, leading to controversy regarding the fluorination of drinking water.
