| 11. | The systematic name of this enzyme class is "'hydroxypyruvate aldose-ketose-isomerase " '.
|
| 12. | The resulting molecule has an hemiacetal or hemiketal group, depending on whether the linear form was an aldose or a ketose.
|
| 13. | The systematic name of this enzyme class is "'11-deoxycorticosterone aldose-ketose-isomerase " '.
|
| 14. | The systematic name of this enzyme class is "'D-glucuronate aldose-ketose-isomerase " '.
|
| 15. | This isomerization of a ketose to an aldose proceeds through an " cis "-enediol ( ate ) intermediate.
|
| 16. | An aldose differs from a ketose in that it has a carbonyl group at the end of the carbon chain instead of in the middle.
|
| 17. | At equilibrium the aldose and ketose form a mixture which in the case of the glyceraldehyde and dihydroxyacetone is also called "'glycerose " '.
|
| 18. | A reducing end of a carbohydrate is a carbon atom that can be in equilibrium with the open-chain aldehyde ( aldose ) or keto form ( ketose ).
|
| 19. | Aldolase can also produce DHAP from other ( 3S, 4R )-ketose 1-phosphates such as fructose 1-phosphate and sedoheptulose 1, 7-bisphosphate.
|
| 20. | If the carbonyl is at the very beginning of the chain ( carbon 1 ), the monosaccharide is said to be an aldose, otherwise it is a ketose.
