Q4 (a) Sucrose, common table sugar, is composed of glucose and fructose. Identify the configuration (a or B) of the two anomeric centers of sucrose. Но НО НО- НО НО 0 ОН НО ОН (b) The molecule shown is a monosaccharide: ОН HOH₂C. ОН ОН (i) Is it a pentose or a hexose? (ii) Is it an aldose or a ketose? CHO (iii) Draw the Fischer projection for this molecule. Does it belong to the D- or L-chiral series? Would you expect it to be a natural sugar on the basis of this chirality? (iv) This compound does not exist to any significant extent as the linear form drawn here, but as a mixture of two cyclic furanose forms. Draw the structure for these explaining how they differ.
