| | DL-Leucine Usage And Synthesis |
| Chemical Properties | White crystalline powder | | Uses | DL-Leucine is a racemic mixture of the D- and L- enantiomers of Leucine. DL-Leucine is used to form benzimidazole and pyrimidine hydroxy azo dyes with various transition metals. DL-Leucine may be used for the evaluation of chiral amino acid separation techniques.
DL-Leucine is used for the following applications:
- Used as a standard for the measurement of free amino acids
- Used in the process of tritiated leucine uptake
- Used in solution preparation (various organics were used in different combinations and concentrations to model complex surface tension effects, DL-Leucine is one of them). It is chosen due to its presence in atmospheric aerosols and ice nucleation activity as well as for its surfactant character
| | Definition | ChEBI: A branched-chain amino acid that consists of glycine in which one of the hydrogens attached to the alpha-carbon is substituted by an isobutyl group. |
