Concept introduction:
舧 Formation of isomers is called isomerization. Monosaccharides undergo a series of keto-enol tautomerizations and enolizations and to produce different isomeric forms. In order to preserve the stereochemical nature of the compounds, the formation of such isomeric forms needs to be prevented.
舧 Stereochemistry: A carbon atom is attached to four distinct groups is said to be a stereogenic or chirality center of that molecule. A stereocenter is that point in a molecule where any two groups exchange their positions to form stereoisomers.
舧 The pair of diastereomers that shows different configuration at the chirality center are called epimers. The aldohexoses,

舧 While dissolved in aqueous bases such as pyridine, monosaccharides undergo complex isomerization as they form different enols and keto-enols. Aldonic acids form epimers (usually at the
