WebGlucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose,” also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two. It is therefore called a “ketose” or a “ketohexose.” WebDec 24, 2016 · There are 16 optical isomers of glucose. Explanation: The structure of glucose is We see that carbon atoms 2, 3, 4, and 5 are chiral centres. The maximum number of optical isomers is 2n, where n is the number of chiral centres. In glucose, n = 4, so 24 = 16 possible isomers. Here are their structures. The names of the above …

WebAs a result, C 1 becomes chiral or asymmetric and thus has two possible arrangements of H and OH groups around it.
