Web6 apr. 2024 · Molecules Of Taste -- Glucose. Glucose (C6H12O6) contains six carbon atoms and an aldehyde group and is therefore referred to as an aldohexose. The glucose molecule can exist in an open-chain (acyclic) and ring (cyclic) form(in equilibrium), the latter being the result of an intramolecular reaction between the aldehyde C atom and the C-5 … WebThere are two chiral carbons, so there are 22 = 4 possible optical isomers. However, two of the structures are identical. They are the same meso compound. So there are only three isomers. Both of the enantiomers are diastereomers. In each case, the meso compound is not optically active, while its diastereomeric partner is optically active.
