Application

DL-Cysteine hydrochloride is used in cell culture. It is also used in photochemical vascular injury (performed using dl-cysteine hydrochloride along with other components). It may be used in the preparation of DL-4-carboxy-3-formyl-2,2,-dimethylthiazolidine.

Actions biochimiques/physiologiques

DL-Cysteine is a racemic mixture of the proteinogenic amino acids L-cysteine and the non-proteinogenic D-cysteine. DL-Cysteine is used as an organic reagent and in comparative physicochemical analysis of processes such as crystallization.
NMDA glutamatergic receptor agonist that is also an agonist at AMPA glutamatergic receptors at high concentration.

The structural complexity of composite biomaterials and biomineralized particles arises from the hierarchical ordering of inorganic building blocks over multiple scales. Although empirical observations of complex nanoassemblies are abundant, the physicochemical mechanisms leading to their geometrical complexity are still puzzling
