Problem 1
Draw the mirror images of glucose and fructose. Are glucose and fructose chiral? Do you expect them to be optically active?
Problem 2c
How many asymmetric carbons and stereoisomers are there for an aldohexose? For a ketohexose?
Problem 3
(a) There is only one ketotriose, called dihydroxyacetone. Draw its structure.
(b) There is only one aldotriose, called glyceraldehyde. Draw the two enantiomers of glyceraldehyde.
