Carbohydrates or sugars can be represented into two forms Fischer projections (open chain) or Haworthprojections (ring structures). Let us identify the functional group present in carbohydrates Fischer projectionsof D-allose and D-fructose.H,CH-C-OHC=0H-C-OHHO-CH-C-OHH-C-OHH C+OHH-C-OHHyC,HO.HOD-alloseD-fructosea.) The functional group present in D-allose isb.) The functional group present in D-fructose isc.) The functional group common for D-allose and D-fructose is There are twenty amino acid that we will encounter in the unit about proteins.
