Description

General description

L-Isoleucine is an essential amino acid used as a supplement in sports nutrition. It is one of the free-amino acids found in common buckwheat.

Application

• Enhanced protein-metabolite correlation analysis: To investigate the association between Staphylococcus aureus mastitis and metabolic immune pathways.: This article discusses the metabolic pathways associated with bacterial infections in livestock, potentially useful for chemists studying metabolic pathways and their linkage to immune responses (Chen et al., 2024).


• Probing pharmaceutically important amino acids L-isoleucine and L-tyrosine Solubilities: Unraveling the solvation thermodynamics in diverse mixed solvent systems.: This study explores the solubility and solvation thermodynamics of l-isoleucine, providing critical data for chemists working with pharmaceutical formulations and solubility studies (Chakraborty et al., 2024).
