Epimerization is a foundational concept in chemistry and biochemistry that describes the interconversion between epimers — compounds that differ in configuration at exactly one stereogenic centre. In everyday terms, this means a single atom’s three-dimensional arrangement is flipped in such a way that the two forms are non-superimposable mirror images at one specific carbon centre.…
