1 open chain structure of D-iodose   D-iodose 2 Rotated 90° clockwise direction    3 Connect C1 carbon with oxygen of C5 carbon by putting C1 OH downward(alpha form) 4  Stretched the structure in a way as bath tub bay making base as 2,3 carbon 5 Assign the H and OH group to each carbon as same (if H is above then put in upward , if H is below then put in downward, similarly for OH) as above structure 6 The completed structure given below is the HAWORTH STRUCTURE of D-iodose Conversion of Haworth to chair form 1 Stretch C1 carbon downward and C4 carbon upward direction 2 Now assign H and OH groups to each carbon as same way in above Haworth projection  This is the final chair form of  alpha D-iodose Now we can convert any following aldohexose sugar to their chair form by the above simple steps.

How to understand the chair form of glucose Generally for us it is easier to understand the structure in 2D. But if we have to know about the configuration (arrangement of substituents)  of a molecule in 3D which is already represented on paper in 2D then we have to visualize that molecule in mind in 3D . This visualization helps to understand the correct structure of molecule. So let's go forward for the same.                            Glucose which has the molecular formula=  C 6 H 12 O 6 . It is aldohexose sugar which contains an aldehyde and 5 -OH  groups attached to 5 different carbon.Its linear structure is given below                                                                         ...
