Any compound structurally derived from 1H-indole3-acetamide or 1H-2-acetamide substituted in both of the following ways: at the nitrogen atom of WebD and L are relative configurations of the two enantiomers of a chiral compound. Ultimately, the D isomer is related to D (+)-Glyceraldehyde. In sugars the “Penultimate” chiral carbon bears this relation. The sugars in our world are all D-sugars, amino acids are all L-amino acids. 1 Sponsored by Gundry MD
