Application

L-Cysteine hydrochloride monohydrate has been used in a protocol for the separation of dorsal root ganglion neurons (DRGs). It has also been used in a study to examine its effect as an inhibitor in preventing enzymatic browning in apples.

Biochem/physiol Actions

NMDA glutamatergic receptor antagonist.

General description

L-Cysteine hydrochloride monohydrate (LCHCMH) is a water soluble salt of the non-essential amino acid, L-cysteine. It is widely employed in the medicine industry. The thermodynamic features of a solution of LCHCMH in water have been reported. It crystallizes in the orthorhombic system with space group P212121. Its nonlinear optical (NLO) property has been investigated in a single crystal grown by unidirectional Sankaranarayanan-Ramasamy (SR) technique.
