The l is used in organic chemistry to represent a single chiral carbon atom. As a result, many chiral drugs, including the malaria drug artemisinin, have the l-stereochemistry. L-amino acids are the building blocks of proteins and are critical to life. L-amino acids are isomers of D-amino acids, and they are distinguished from each other by the relative locations of their chiral carbon atoms.
