General description

L-cysteine is a sulfur-containing amino acid.

Application

The addition of L-cysteine hydrochloride to wheat flour led to the reduction in the peak viscosity during the analysis of its pasting characteristics using rapid visco analyzer (RVA).

Biochem/physiol Actions

NMDA glutamatergic receptor agonist that is also an agonist at AMPA glutamatergic receptors at high concentrations.
