H-Leu-Tyr-OH is a biphasic response amide with two phenyl groups and a primary amino group. It is most active at pH 6.5, but can be used at higher or lower pHs. The rate of H-Leu-Tyr-OH formation is highest in triticum aestivum (wheat) butyric acid extract. H-Leu-Tyr-OH has been shown to have excitatory effects on plant physiology, which may be due to its ability to bind to the specific antibody against acetylcholine receptors.
