- Two cyclic stereoisomersTwo cyclic stereoisomers can form from each straight-chain monosaccharide; these are known as anomers. In an aqueous solution, an equilibrium mixture forms between the two anomers and the straight-chain structure of a monosaccharide in a process known as mutarotation.saylordotorg.github.io/text_the-basics-of-general-organic-and-biological-chemistry/s…

25.5: Cyclic Structures of Monosaccharides - Anomers
When D-glucose cyclizes it forms a 37/63 mixture of the alpha and beta anomer respectively. The beta anomer is preferred because β -D-glucopyranose is the only aldohexose which can be drawn with all its bulky substituents (-OH and …

25.5 Cyclic Structures of Monosaccharides: Anomers
When an open-chain monosaccharide cyclizes to a pyranose form, a new chirality center is generated at the former carbonyl carbon and two diastereomers, called anomers, are …

These two stereoisomers of a cyclic monosaccharide are known as anomers; they differ in structure around the anomeric carbon —that is, the carbon atom that was the carbonyl carbon atom in the straight-chain form.
7.1: Monosaccharides and Disaccharides - Biology LibreTexts
If a monosaccharide, disaccharide, or even polysaccharide has a least one hemiacetal link (for instance the second sugar in lactose), it is a reducing sugar, as the monomer with the cyclic …
In monosaccharides the joining of one hydroxyl group (--C--OH) to the carbonyl carbon (--C~O) produces a cyclic structure. The properties of monosaccharides, both in the combined and …
