Amylase Methodologies

A

Continuous Monitoring

SACC

21
Q

Coupling of several enzyme to measure enzyme activity

A

Continuous monitoring

22
Q

measures the disappearance of starch substance

23
Q

measures the appearance of substance (starch —> reducing sugar)

A

Saccharogenic

24
Q

measures increasing color from product
(Insoluble starch dye - soluble starch dye)

25
Iodine reacts only with
Complex sugars
26
Amyloclastic: Once the enzyme attacks the substrate it will result to
decrease substrate concentration
27
Amyloclastic: If the substrate concentration decreases what will happen next
Starch releases simple sugars = Iodine will not react with it = Decrease color intensity
28
Amyloclastic: Substitute for Starch as substrate
Glycogen
29
If glycogen will react to iodine it will produce
Mahogany brown color
30
Saccharogenic: once the amylase attacks starch, starch will release
reducing sugar
31
Saccharogenic: Reducing sugar from Starch has what kind of relationship to enzyme activity
Directly proportional
32
Chromogenic: Insoluble starch dye will produce fragment, fragment is responsible for
Color reaction
33
Chromogenic: product produced has what kind of relationship to enzyme activity
Directly Proportional
34
Continuous Monitoring Assay: Last enzyme involved in reaction
Oxidoreductase
35
Continuous Monitoring Assay: Last reaction
conversion of coenzyme (NAD --> NADH)
36
Continuous Monitoring Assay: Measures absorbance at?
Increase @340 nm
37
Continuous Monitoring Assay: Second substrate, indicator used
A-glucosidase Hexokinase G-6-PD
