Descripción general

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.

Aplicación

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.

Chronic wounds are a major global health problem with the presence of biofilm significantly contributing to wound chronicity. Current treatments are ineffective in resolving biofilm and simultaneously killing the bacteria; therefore, effective biofilm-resolving drugs are needed. We have previously shown
