| 1. | Payen discovered the first enzyme, diastase, in 1833.
|
| 2. | French chemist Anselme Payen was the first to discover an enzyme, diastase, in 1833.
|
| 3. | The presence of the glycogen can be demonstrated with positive PAS staining and negative PAS diastase staining.
|
| 4. | The diastase negative slide will show a magenta staining where glycogen is present within a section of tissue.
|
| 5. | The slide that has been treated with diastase will lack any positive PAS staining in those locations on the slide
|
| 6. | Bee digestive enzymes-invertase, amylase, and diastase-and gastric acid hydrolyze sucrose to a mixture of glucose and fructose.
|
| 7. | The enzyme was originally intended for use in distilleries, but was more successfully marketed as " Taka-diastase " for dyspepsia.
|
| 8. | PAS diastase stain ( PAS-D ) is PAS stain used in combination with diastase, an enzyme that breaks down glycogen.
|
| 9. | PAS diastase stain ( PAS-D ) is PAS stain used in combination with diastase, an enzyme that breaks down glycogen.
|
| 10. | Overheating is indicated by change in enzyme levels, for instance, diastase activity, which can be determined with the Schade or the Phadebas methods.
