Application

Cysteamine hydrochloride has been used in the in-situ generation of chiral cysteamine-capped cadmium sulfide quantum dots (CA-CdS QDs) for the sensing of Cd2+ and S2-.

Biochem/physiol Actions

Cysteamine hydrochloride is derived from the degradation of coenzyme A endogenously. Its concentration in plasma is low. It is commonly used as a drug for the orphan disease cystinosis, a lysosomal storage disorder, in which cysteamine decreases intralysosomal cystine accumulation.
Cysteamine is an aminothiol that can reduce important oxidized disulfide molecules such as cystine to yield cysteine. Cysteamine is used in a wide range of applications from regulation of gene expression, to depletion of somatostatin, to coating of nanoparticles.
