Yes, L-glucose also has α and β anomers.

Yes, L-glucose also has α and β anomers.

The structures of the α and β anomers of D-glucose are

Note that in the α isomer the $"OH"$ on $"C-1"$ is on the side opposite to the $"CH"_2"OH"$ group ("down").

In the β isomer, the $"OH"$ on $"C-1"$ is on the same side as the $"CH"_2"OH"$ group ("up").

In L-glucose, all the orientations are reversed.

What was "up" becomes "down", and what was "down" becomes "up".

F or example, α L-glucose is

and β L-glucose is

Beta
(From web.pdx.edu)

Note that the definitions of α and β stay the same.

α is still opposite to the $"CH"_2"OH"$ , and β is still on the same side as the $"CH"_2"OH"$ .
