(a)
Interpretation:
For the two stereo isomeric ketotetroses, the structure, stereo isomeric relationship and stereo disrupters are needed to be determined.
Concept introduction:
- Ketoses are monosaccharides, which contains
ketone group. - The naming of monosaccharides,
- Prefix: aldo or keto indicates whether the monosaccharide is containing
aldehyde or ketone group. - Suffix: ose indicates the carbohydrates
- Root word: indicate the number of carbons.
- Prefix: aldo or keto indicates whether the monosaccharide is containing
- The stereo-descriptor used for monosaccharides is D or L. it is based on the dextrorotatory glyceraldehyde or levorotatory glyceraldehyde.
- Enantiomers are non-super imposable mirror images of each other.
To determine: the structure of two stereo isomeric ketotetroses.
