A monohydrochloride monohydrate salt of L-histidine. L-Histidine is an essential amino acid. It is widely used as an ingredient in infusion.
L-Histidine monohydrochloride monohydrate has been used as a component of broth to match the tuna meat amino acid composition. It has also been used for partial rescue of the IMPL2 (myo-inositol monophosphatase) phenotype during seed development of Arabidopsis.
