Product Introduction
L-cysteine is mainly distributed in the liver, spleen, and kidneys. It also accumulates in large quantities on the surface of the human body, including the skin, mucous membranes, and the surface of the digestive organs. It can strengthen the body's own defense capabilities and adjust the body's defense mechanisms when foreign matter, including those ingested orally, inhaled from the atmosphere, or invaded by contact with the skin, invades.
Detection Principle
Cysteine reduces phosphotungstic acid DTNB to generate TNB, which has an absorption peak at 405 nm. The content of cysteine can be calculated by measuring the absorbance value at 405 nm.
