WebGlucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose,” also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two. It is therefore called a “ketose” or a “ketohexose.” WebJan 23, 2024 · The four chiral centers in glucose indicate there may be as many as sixteen (2 4) stereoisomers having this constitution.

Explanation: The structure of glucose is We see that carbon atoms 2, 3, 4, and 5 are chiral centres. The maximum number of optical isomers is 2n, where n is the number of chiral centres. In glucose, n = 4, so 24 = 16 possible isomers. Here are their structures. The names of the above …

WebD-Mannose is an epimer of D-glucose because the two sugars differ only in the configuration at C-2. When a molecule such as glucose converts to a cyclic form, it generates a new chiral centre at C-1 . The carbon atom that generates the new chiral centre ( C-1 ) is called the anomeric carbon. Are mannose and galactose enantiomers? WebThe new chiral carbon is produced with both stereochemistries, so the product of a Kiliani–Fischer synthesis is a mixture of two diastereomeric sugars, called epimers. For example, D - arabinose is converted to a mixture of D - glucose and D - mannose .
