👉 In organic chemistry, epimerism is a process by which one molecule can be converted into another in a chemical reaction. This may involve the addition of a different type of substituent, such as an alcohol or an organocarboxylic acid (OCA), to the reactant molecules, resulting in a new compound with a different set of properties. Epimerism is not a physical process but rather a chemical transformation that involves the introduction of a substituent from one molecule into another.
