  • Anomer
    Cyclic sugar variant distinguished by the configuration at a specific ring carbon bonded to two oxygens.
  • Anomeric Carbon
    Ring carbon atom attached to two oxygens, formerly the carbonyl carbon before sugar cyclization.
  • Alpha Anomer
    Form where the ring's key hydroxyl group points opposite to the highest numbered carbon in the structure.
  • Beta Anomer
    Form where the ring's key hydroxyl group points in the same direction as the highest numbered carbon.
  • Cyclization
    Process converting a linear sugar into a ring, creating a new chirality center at a specific carbon.
  • Chirality Center
    Atom in a molecule with four distinct groups, resulting in two possible spatial configurations.
  • Hemiacetal
    Functional group formed when an aldehyde reacts with an alcohol during sugar ring formation.
  • Hemiketal
    Functional group formed when a ketone reacts with an alcohol during sugar ring formation.
  • Hydroxyl Group
    Functional group consisting of an oxygen and hydrogen, crucial for sugar ring formation and configuration.
  • Carbonyl Group
    Functional group with a carbon double-bonded to oxygen, present in linear sugars before ring formation.
  • D Glucose
    Common monosaccharide with an aldehyde group, capable of forming cyclic structures with distinct anomers.
  • Open Chain Sugar
    Linear form of a monosaccharide before cyclization, featuring a carbonyl group.
  • Configuration
    Spatial arrangement of atoms around a chirality center, determining the identity of alpha or beta forms.
  • Nucleophile
    Atom or group that donates electrons to form a bond, such as an alcohol group attacking a carbonyl.
  • Mirror Image
    Relationship between two molecules where each is a non-superimposable reflection of the other, not applicable to anomers.
