Question
Stereochemistry in biological molecules is often denoted by the D- and L- convention, instead of the R- and S- configurations determined by the Cahn-Ingold-Prelog methodology. Naturally occurring α-amino acids are typically in the L-configuration. The Fischer projection of L-alanine is shown. L-alanine H₂N- H3C- HOOC Identify which structures are equivalent to the L-configuration. H COOH H CH3 NH₂ -COOH NH₂ CH3 -H CH3 COOH H -NH₂ H₂N- H CH3 COOH NH₂ H CH3 -COOH
