WebJul 4, 2024 · Stereochemistry of Amino Acids. With the exception of glycine, all the 19 other common amino acids have a uniquely different functional group on the central tetrahedral alpha carbon (i.e. C α ). The C α is termed "chiral" to indicate there are four different constituents and that the Ca is asymmetric. Since the C α is asymmetric there … WebI would identify this as a Carl center, so I put a red star here. The next carbon. It is double bonded to on oxygen, and like I said earlier, we need to have four different groups. But since that is not the case for this particular carbon, it is not a Carl center moving on. We have oxygen that can't be a Carl center.
