Questions

The structure оf оne оf the enаntiomers of psicose is shown below.  Blаnk #1: Is this the D or L enаntiomer of psicose? Blank #2: Define psicose in terms of the number of carbons and its carbonyl functional group (for example, aldopentose).  Blank #3: What is the stereochemical relationship between psicose and fructose, assuming they are both D? (enantiomers, epimers at C-? , diastereomers with more than one different chiral C, structural isomers, different molecules) Blank #4: Write the letter of the cyclic structure shown below that corresponds to a-D-psicose.  Blank #5: Is this a reducing sugar? (yes/no) Blank #6: Does picose undergo mutarotation? (yes/no)
