Stereoisomeric aldohexoses that differ in configuration at only a single carbon are ________.

Question

Quizplus · Accepted Answer

Stereoisomeric aldohexoses that differ in configuration at only a single carbon are called epimers. Epimers are a subtype of diastereomers, which are stereoisomers that are not mirror images of each other, and thus have different physical and chemical properties. Meso compounds are compounds that have chiral centers but also possess internal planes of symmetry, making them achiral overall. Threo sugars are a subclass of diastereomers that have the 2,3- and 4,5- diol groups on the same side of the Fischer projection. Enantiomers are stereoisomers that are non-superimposable mirror images of each other and have identical physical and chemical properties (except for their interaction with polarized light). Constitutional isomers have the same molecular formula but different connectivity of atoms.
