A researcher conducted an experiment and needed to use L-Leucine. He is able to scavenge four bottles that have faded labels and impossible to identify which enantiomer of leucine or isoleucine it contains. The researcher remembers his melting point lab and decides to classify the identity of the compounds based on the melting point. He experimentally determines a melting point for each bottle: (see table or image attached)i. 291-295 °Cii. 283-287 °C iii. 289-291 °C iv. 292-294 °C Which of the following bottles is L-Leucine?
7. Dihydrocarveol is another natural product found in spearmint oil, but in minor amounts. dihydrocarveol a) Determine the R or S configuration of each chiral center in dihydrocarveol. b) When separating the components of spearmint oil by column chromatography, in what order would you expect carvone, limonene, and dihydrocarveol to elute? c) Which compound would you expect to have the lowest Rf value by TLC: carvone, limonene, or dihydrocarveol?
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. Historically, the glyceraldehyde enantiomer that rotated plane polarized light clockwise was arbitrarily designated as D and the other enantiomer was designated as the L configuration. The D‑glyceraldehyde Fischer projection is shown. D‑glyceraldehyde
