  • What is a monosaccharide derivative?
    A monosaccharide derivative is a chemically modified simple sugar that deviates from the formula CnH2On.
  • Name the five major groups of monosaccharide derivatives.
    The five major groups are sugar phosphates, sugar alcohols, deoxy sugars, amino sugars, and sugar acids.
  • What is a sugar phosphate?
    A sugar phosphate is a carbohydrate covalently attached to a phosphate group.
  • Where are sugar phosphates found in biological molecules?
    Sugar phosphates are part of the structure of nucleotides, which make up nucleic acids like DNA.
  • Why are sugar phosphates important in metabolism?
    Sugar phosphates are important intermediates in carbohydrate metabolism and catabolism.
  • How is D-glucose converted to D-glucose 6-phosphate?
    D-glucose is converted to D-glucose 6-phosphate by phosphorylation, attaching a phosphate group to the molecule.
  • What is a sugar alcohol (aldotol)?
    A sugar alcohol is a sugar whose carbonyl group is reduced to an alcohol group, resulting in an OH group on every carbon.
  • What suffix is commonly used for sugar alcohols?
    Sugar alcohols usually have the suffix 'itol' added to their names.
  • How is sorbitol formed from D-glucose?
    Sorbitol is formed by reducing the aldehyde group of D-glucose to an alcohol group.
  • What is a deoxy sugar?
    A deoxy sugar is a sugar missing at least one hydroxyl group, usually replaced by a hydrogen atom.
  • Which deoxy sugar is a key component of DNA?
    2-deoxy-D-ribose is the primary building block of DNA in all organisms.
  • What is an amino sugar?
    An amino sugar is a sugar containing an amino group instead of a hydroxyl group at a specific position.
  • Where are amino sugars commonly found?
    Amino sugars are commonly found in oligosaccharides and polysaccharides, such as chitin.
  • What is a sugar acid?
    A sugar acid is a carbohydrate with one or more carboxylic acid groups.
  • What are the three types of sugar acids and how are they classified?
    The three types are aldonic acids (C1 oxidized), uronic acids (highest numbered carbon oxidized), and alderic acids (both ends oxidized).
