Vue d’ensemble

Product Description

Cysteine is a non-essential amino acid that can be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available. Cysteine is commonly used as a precursor in the food and pharmaceutical industries. Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours.

Product Application
NMDA agonist that is an agonist at quisqualate receptors at high concentration.
