Anwendung

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

Transfusion-associated graft-versus-host disease (TA-GVHD) is usually a fatal outcome of blood transfusion therapy, caused by viable leucocytes contained in the donor blood. Most cases of TA-GVHD occur when less than 4-d-old blood is transfused. We therefore examined the molecular changes

Sodium-coupled transporters are ubiquitous pumps that harness pre-existing sodium gradients to catalyse the thermodynamically unfavourable uptake of essential nutrients, neurotransmitters and inorganic ions across the lipid bilayer. Dysfunction of these integral membrane proteins has been implicated in glucose/galactose malabsorption, congenital
