Chiral carbons in fructose
WebHere, everything is the same except for the configuration of the chiral center at carbon #2. The two sugars differ at only one of the four chiral centers, so again they are diastereomers, and more specifically they are epimers. D-glucose and L-glucose are enantiomers, because they differ at all four chiral centers. WebDec 20, 2024 · The six-carbon monosaccharide fructose contains a ketone in its open-chain form and therefore produces a five-membered ring in its cyclic form. Disaccharides are two monosaccharides bonded together.
