Aldehyde or Ketone derivatives of the higher polyhydric alcohols or compounds which yield these derivatives on hydrolysis.
Monosaccharides: Can be classified as trioses, tetroses, pentoses, hexoses and heptoses depending upon the number of carbon atoms, and as aldoses or ketoses, depending upon whether they have an aldehyde or ketone group.
Mutarotation: The changes of the initial optical rotation that takes place in an aldohexose e.g. glucose (α-form) when put (dissolved) in water and the solution is put in optical path (plane polarized light). Sugar α -glucose will change into β-form and a mixture of both (α and β).
