WebFor the 20 α-amino acids that occur naturally in proteins, if we focus on the α-center, a chirality center, and draw the Fischer projection putting the -CO 2 H group up, then the ammonium group, NH 3 +, will be on the left, making it like L-glyceraldehyde where the -OH is on the left (review?). Hence, we have the L-amino acids. WebIn Fischer’s original assignment of the glyceraldehyde enantiomers, he labeled the dextrorotatory (+) isomer as D and the levorotatory (−) isomer as L. These labels are … melda ulusoy mathworks
