The prefixes 'erythro' and 'threo' are used for distinguishing a pair of enantiomers containing two chiral carbon atoms when two of the atoms or groups on each chiral carbon atom are the same while the third is different. The stereoisomer, in which the two identical groups are on the same side of the Fischer projection formula, is called the erythro isomer while the isomer, in which the two identical groups are on the opposite sides of the Fischer projection formula, is called the threo isomer.
