                                Despite having the same chemical formula ($C_6H_{12}O_6$), the monosaccharide glucose is significantly more stable than its epimer, galactose. This difference in stability is a direct result of their stereochemical arrangement and the resulting energetic strain in their cyclic chair conformations.
