Description

Activating quisqualate-sensitive NMDA receptors at elevated concentrations, DL-Cysteine (CAS 3374-22-9) modulates glutamatergic neurotransmission in excitatory synaptic pathways.

Application

DL-Cysteine (CAS 3374-22-9) drives pharmaceutical synthesis by serving as a key sulfur-containing precursor for antioxidants and detoxifying agents that combat oxidative stress. It supports cellular redox balance. In food, it enhances flavor and extends shelf life. Skincare formulations leverage its antioxidant power to reduce aging signs. Researchers use it in cell culture to sustain growth via sulfur supply. Its neuroprotective potential is under active study for Alzheimer’s and Parkinson’s therapies.
