Valine

It has been proven in numerous studies that in situations of abiotic stress plants accumulate valine, as well as alanine and leucine. Isoleucine is part of the subgroup of branched chain amino acids (in English they are called Branched-Chain Amino Acids BCAA), these amino acids serve as a substrate to synthesize many other metabolites. For example, leucine is a precursor of alcohols, and other compounds, which improve the organoleptic qualities of the fruits. In situations of abiotic stress, plants produce a large number of branched chain amino acids (valine, isoleucine, etc.) that are used by the plant to synthesize stress response proteins.
