WebJul 22, 2015 · In the cyclic form of a sugar, the anomeric carbon is the carbon that was part of the carbonyl group in the straight-chain structure. For example, the linear structure of glucose is (from www.chem.wisc.edu) When the chain converts to a ring, C-1 becomes a chiral centre. (from science.uvu.edu) C-1 is the anomeric carbon. In D-fructose, the …

Identify the … WebCarbohydrates have one or more chiral centers- carbons with 4 different groups attached, giving rise to the possibility of stereoisomers Generally, a compound containing “n” chiral centers can maximally have 2 “n” stereoisomers. Enantiomers are stereoisomeric compounds whose structures are nonsuperimposible mirror images of each other.
WebPossible Answers: Three Four Two Five One Correct answer: Two Explanation: A stereocenter exists when the central atom is bound to four unique substituents. In the given molecule, the carbons are numbers from left to right. Carbons 1, 3, 5, 6, and 8 are all bound to at least two hydrogen atoms and cannot be stereocenters.
WebJun 14, 2014 · Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images).
