QJEEM06Chf94a: JEE Main 2006 Chemistry - Class 12 JEEM06Chf94a Solution: The term anomers of glucose refers to

The term anomers of glucose refers to

Multiple Choice Options

  • A isomers of glucose that differ in configurations at carbons one and four (C-1 and C-4)
  • B a mixture of (D)-glucose and (L)-glucose
  • C enantiomers of glucose
  • D isomers of glucose that differ in configuration at carbon one (C-1)

Step-by-Step Verified Solution

Cyclization of the open chain structure of D-(+)- glucose has created a new stereocenter at C1 which explains the existance of two cyclic forms of D-(+)- glucose, namely α− and β−. These two cyclic forms are diasteromers, such diasteromers which differ only in the configuration of chiral carbon developed on hemiacetal formation (it is C1 in glucose and C2 in fructose) are called anomers and the hemiacetal carbon (C1 or C2) is called the anomeric carbon.
