Description

General description

L-cysteine is a sulfur-containing non-essential amino acid. Its ability to reduce colitis symptoms is being assessed for potential use in treating inflammatory bowel disease (IBD).

Naturally occurring non-essential amino acid.

Application

L-cysteine can be used as a cysteine source to prepare L-cysteine functionalized gold nanoparticles for use as probes in the colorimetric detection of Hg²⁺ in aqueous solution.

Biochem/physiol Actions

NMDA glutamatergic receptor agonist.
