difference between DL and dl systems in stereochemistry?

Answer 1

D and L relate the structure of a specific molecule to the two geometric isomers of glyceraldehyde. So, with simple sugars, the D and L designations describe the geometric orientation of the chiral carbon most distant from the carbonyl group of the sugar molecule.

d and l indicate the specific effect of the molecule on plane-polarized light. A molecule which is designated "d" rotates polarized light to the right, while one designated "l" rotates light to the left.

Answer 2

Dl Systems

Answer 3

D/L is older method which is describe accordind to reference which is glycerlyde. and modified by now R/S system. while d/l is physical process which is determined by polrimeter. which rotate the plane plorize light left or right,
