Amino acids are biologically active molecules. 19 of the 20 common amino acids have a chiral alpha carbon, 2 amino acids (Leucine and Threonine) have a second chiral center in their side chain. This video shows you how to
- Find R/S for 3-D amino acids
- Find R/S and D/L for amino acid Fischer projections
- Trick to quickly convert R/S to D/L amino acids

Hello,
Thanks for the videos. A quick question. Towards the end of the video you said that if you have an S-amino acid, you can instantly deduce that the Amino acids Is L-amino acid. Does this mean that you can’t have a D-amino acid with S configuration. I am confused
