Transcribed Image Text:The image shows the chemical structures of two stereoisomers of a sugar molecule, specifically aldotetroses.
1. **Left Structure:**
- This structure is a linear form of an aldotetrose.
- The molecule consists of four carbon atoms.
- From left to right, the configuration at each chiral center is:
- The first carbon (C2) has an -OH group on the right (R-configuration).
- The second carbon (C3) has an -OH group on the left (S-configuration).
- The third carbon (C4) has an -OH group on the left (S-configuration).
- The fourth carbon is part of an aldehyde group (CHO).
2. **Right Structure:**
- This structure is also a linear form of an aldotetrose.
- The molecule consists of four carbon atoms.
- From left to right, the configuration at each chiral center is:
- The first carbon (C2) has an -OH group on the left (S-configuration).
- The second carbon (C3) has an -OH group on the right (R-configuration).
- The third carbon (C4) has an -OH group on the left (S-configuration).
- The fourth carbon is part of an aldehyde group (CHO).
These structural formulas help illustrate the spatial arrangement of hydroxyl groups, which is critical for determining the properties and functions of different sugar isomers.
Expert Solution
Step 1
Diastereomeric compounds can be defined as stereoidomers with different absolute configuration at at least one carbon center.
They are chemically and physically distinguisable from the ennantiomers .
