WebClassification Aldohexoses. The aldohexoses are a subclass of the hexoses which, in the linear form, have the carbonyl at carbon 1, forming an aldehyde derivative with structure H–C(=O)–(CHOH) 5 –H. The most important example is glucose.. In linear form, an aldohexose has four chiral centres, which give 16 possible aldohexose stereoisomers (2 … WebApr 6, 2024 · If we number the carbon atoms from the top in each structure, the carbon numbered 2,3,4 and 5 are chiral in glucose as they have 4 different atoms or molecules attached to them. Similarly, carbon numbered 1,3,4,5 are chiral in fructose. Hence, the number of chiral atoms in glucose and fructose are 4 each. Additional information:
