Chiral centers for glucose
WebHow many chiral centers are there in the open-chain form of glucose? In the cyclic form? Open chain: 4 Cyclic: 5. How does the cyclization of sugars introduce a new chiral center? Two different orientations with respect to the sugar ring are possible for the hydroxyl group at the anomeric carbon. The two possibilities give rise to the new ...

WebJan 3, 2015 · One example of a chiral molecule is glucose, that naturally only occurs in the so-called right-hand variety, called D-glucose or dextrose (dexter=Latin for right). It is possible to make L-glucose (its mirror-image) by chemical synthesis. The human body cannot use L-glucose. It tasts just as sweet, but no calories can be gained from it. WebC. glucose which of the following monosaccharides has a structure in which two or more chiral centers are present?

WebExplanation: Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other. For example, the aldopentoses each contain three chiral centres. Thus, D-ribose is a diastereomer of D-arabinose, D-xylose, and D-lyxose. Epimers are diastereomers that contain more than one chiral center but differ from ...
