"網頁3. d- l- Nomenclature as well as (+), (-) refer to a physical property of the molecule, its optical rotation. Optical rotation is a result of chirality, a topological property of the molecule. So d-, l- is something that you can generally measure with a polarimeter. If you have a 1:1 mixture of the 2 enantiomers then you will see zero rotation ... " - Stereochemistry vs chirality

The reason cysteine is different is that it has a sulfur atom at the second position of the side chain, which has a larger atomic number than that of the groups at the first carbon. Following the naming convention, this makes the molecule (R) rather than (S).
