Monosaccharides

  • These are the simple sugars that cannot be broken down through the hydrolysis reaction.
  • They do not have any covalent bond.
  • These are the monomers that would condense via the glycosidic bond (a type of covalent bond) to form polymers of carbohydrates.
  • They are represented by the formula (CH2O)n.
  • The smallest molecules usually considered to be monosaccharides are those with n = 3.
  • Monosaccharides are also classified on the basis of the carbonyl - aldehyde (-CHO) or ketose (-COR) group.
  • Glyceraldehyde is a triose with an aldehyde group.
  • Dihydroxyacetone is a triose with a ketose group.
  • Glucose is a hexose with an aldehyde group.
  • Fructose is a hexose with a ketone group.

 

 TIP: Carbons in a monosaccharide are numbered such that the aldehyde group is carbon number one or the ketone group is carbon number two.

 

 

 

 

Glucose contains aldehyde group which would be represented at C-1 in its structure.
