Anomerization is a chemical process in which anomer isomers interconvert. Anomers are a special type of epimers, which are diastereomers that differ in configuration at the anomeric carbon of a sugar molecule. Anomerization is typically reversible and often involves the ring-opening and closing of cyclic sugar structures.
What else can I help you with?
What is the difference between epimer anomer and why anomerisation of glucose is not called epimerisation?
An Epimer is a stereoisomer of another compound that varies in its configuration at only one of the chiral centres. For example beta-D-glucopyranose and alpha-D-mannopyranose are epimers. An anomer is also a type of epimer,it is more specifically used in sugar chemistry.It is a stereoisomer of a saccharide (in the cyclic form) that differs only in its configuration at the hemiacetal or hemiketal carbon, also called the anomeric carbon.
What does the term anomeric effect refer to?
In organic chemistry, the anomeric effect or Edward-Lemieux effect is a stereoelectronic effect that describes the tendency of heteroatomic substituents adjacent to a heteroatom within a cyclohexane ring to prefer the axial orientation instead of the less hindered equatorial orientation that would be expected from steric considerations. This effect was originally observed in pyranose rings by J. T. Edward in 1955; at that time, N.-J. Chii and R. U. Lemieux began to study the anomerization equilibria of the fully acetylated derivatives of several aldohexopyranoses. The term "anomeric effect" was introduced in 1958. The anomeric effect received its name from the term used to designate the C-1 carbon of a pyranose, the anomeric carbon. Isomers that differ only in the configuration at the anomeric carbon are called anomers.
