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 …
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. high or low waist jeansWebisomers that are different at every chiral center (for example, L-glucose and R-glucose) What are epimers?
