D-Glucose is NOT L-glucose.


D-Glucose and L-glucose are non-superimposable mirror image isomers of each other.

You can see this in the two Fischer projections shown below.

You can recognize D-glucose in a Fischer projection because the highest-numbered chiral carbon (carbon 5) has the #"OH"# group on the right hand side of the vertical carbon chain.

L-Glucose has that #"OH"# group on the left, and every other chiral carbon has the #"OH"# on the side opposite to that of the corresponding carbon in D-glucose.
