PHYSICAL PROPERTIES

  • All monosaccharides which have an asymmetric carbon are able to rotate polarized light either to left side (laevorotatory) or right side (dextrorotatory).
  • Dextrorotatory sugars are more common as compared to laevorotatory ones.
  • Laevorotatory fructose (L-fructose) is present in honey and is called laevulose.
  • Pentoses, hexoses and heptoses exist in two forms, Open chain and Ring form.
  • Ring form is again of two types :

(a) Pyranose. Hexagon with 5 carbons and one oxygen.

(b) Furanose. Pentagon with 4 carbons and one oxygen.

  • Both words are given by Howarth.
