Application
- L-Valine has been used as a standard in thin layer chromatography.
- It has been used as a supplement in Grace′s antheraea medium for the culture of cells and tissue from invertebrates.
- It has been used in the preparation of starvation media to study the role of relA gene in antibiotic resistance in E. coli.
Biochem/physiol Actions
Valine is an essential amino acid, involved in the biosynthesis of glutamine and alanine. Valine being a branched-chain amino acid (BCAA) maintains a balance among the BCAAs. L-Valine serves as an energy fuel. Long term deficiency of L-Valine leads to growth failure, organ damage and loss of muscle mass.

Short-chain acylations of lysine residues in eukaryotic proteins are recognized as essential posttranslational chemical modifications (PTMs) that regulate cellular processes from transcription, cell cycle, metabolism, to signal transduction. Lysine butyrylation was initially discovered as a normal straight chain butyrylation (Knbu).

Adequate protein intake is crucial for the survival and well-being of animals. How animals assess prospective protein sources and ensure dietary amino acid intake plays a critical role in protein homeostasis. By using a quantitative feeding assay, we show that
