Epimers are diastereoisomers that differ in the configuration at one stereocenter, while enantiomers are mirror images of each other with opposite stereochemistry at all stereocenters. Epimers have different physical and chemical properties, while enantiomers have identical physical and chemical properties except for their interaction with plane-polarized light.

Are D-glucose and D- mannose enantiomers?
Yes, D-glucose and D-mannose are aldohexose monosaccharides that are enantiomers of each other. They have the same molecular formula but differ in the arrangement of functional groups around a chiral carbon atom, making them optical isomers.
Why are enantiomers of biological interest?
Enantiomers have the same chemical and physical properties but interact differently with biological systems due to their three-dimensional structure. This can lead to differences in biological activity, such as in drug effectiveness and toxicity. Understanding the differences between enantiomers is important for drug development and in biological processes.
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.
Do enantiomers have the same biological properties?
Enantiomers are mirror-image molecules that have the same chemical formula but differ in their spatial arrangement. Due to this difference in spatial orientation, enantiomers can have different biological properties, as they may interact differently with proteins and enzymes in the body. This difference in biological activity is known as enantiomeric or chirality effects.
What are epimers?
Epimers are a type of stereoisomer that differ only in the configuration around one specific carbon atom. This change in configuration results in the molecules having different spatial arrangements and therefore different chemical and physical properties. An example of epimers is D-glucose and D-mannose.
Are D-glucose and D- mannose enantiomers?
Yes, D-glucose and D-mannose are aldohexose monosaccharides that are enantiomers of each other. They have the same molecular formula but differ in the arrangement of functional groups around a chiral carbon atom, making them optical isomers.

Are Anomers and Epimers same?
Yes, anomers and epimers are the same. In chemistry, anomers are special types of epimers.
Why all anomers are epimers but all epimers are not anomers?
Epimers are two diastereomers that differ at one stereogenic center (a chiral carbon). An anomer is is an epimer that is created after cyclization.-that is the new sterogenic center is created by a cyclization reaction.Added:This above might be true, but is an answer to the OTHER question:'Why all anomers are epimers but notall epimers are anomers'in stead of the original question:'Why all anomers are epimers but allepimers are not anomers'This origional is not fully logic when the ambiguous word 'all' is wrongly interpreted.

Difference between l-limonene and s-limonine?
l-limonene and s-limonine are mirror-image isomers known as enantiomers. They have the same chemical formula but differ in their arrangement of atoms in three-dimensional space. This difference gives them unique properties, such as different odors and biological activities.
How optical isomers arise?
Optical isomers, also known as enantiomers, arise due to the presence of a chiral center in a molecule, which results in non-superposable mirror images. Chirality results from the spatial arrangement of different groups around a central atom, leading to distinct left- and right-handed versions of the molecule. This structural difference gives rise to different physical and biological properties between the two enantiomers.
What are Anomers and Epimers?
Anomers are cyclic forms of carbohydrates that differ in the configuration of the anomeric carbon (carbon bearing the carbonyl group). Epimers are carbohydrates that differ in the configuration of one chiral center other than the anomeric carbon. Both anomers and epimers are important in carbohydrate chemistry and can have different biological properties.
How many enantiomers are possible for the aldoheptoses?
Aldoheptoses have seven carbon atoms and one chiral center, so they can have a maximum of 2^1 = 2 enantiomers.
What isomers that are mirror images of each other?
Chiral molecules have mirror-image isomers
