separation of D-/L-glucose

Hi!

How can we separate D- and L-glucose from each other and calculate the concentrations of them? I now that one method is based on polarimetry but are there other methods?

maybe it isn't today the main topic but it is still useful to give some thought for the question. In our school we got this topic as a homework and it forces as to think about dna, rna and proteins in general. and I think it is useful....
:wink: Could someone tell me why protein didn't came first?
