D and L stereoisomers

  1. Sep 16, 2009 #1
    I was wondering about this earlier today: how do they (IUPAC?) decide which stereoisomer is D and which is L? I understand the difference between the two, but I don't know how to determine which is which. I imagine it has something to do with chiral priority, but could someone explain, or give me a resource on this?
