What is L-Cysteine (13C3)?

The Uses of L-Cysteine (13C3)

L-Cysteine-13C3 is the isotope labelled analog of L-Cysteine (C995000); 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. L-Cysteine is commonly used as a precursor in the food and pharmaceutical industries. L-Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours.
