L-Leucine 98%

What is L-Leucine? It is an essential amino acid that is used in the biosynthesis of proteins. Leucine is an α-amino acid, meaning it contains an α-amino group (which is in the protonated −NH₃+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isobutyl group, making it a non-polar aliphatic amino acid.

Consistent Quality: We provide only high-quality L-Leucine, ensuring reliable and consistent performance for all applications.
