Is L-cystine and L cysteine the same?
L-cystine is a dimer consisting of two oxidized L-cysteine molecules, linked by a disulfide bridge. One more step is required to produce L-cysteine. The dimer L-cystine is reduced by electrolysis to the monomeric L-cysteine. L-cysteine is one of the 20 natural amino acids that are the building blocks of proteins.
Does cystine cause kidney stones?

What is L-cystine used for?
L-cystine is the L-enantiomer of the sulfur-containing amino acid cystine. It has a role as a flour treatment agent, a human metabolite, a Saccharomyces cerevisiae metabolite, a mouse metabolite and an EC 1.2. 1.12 (aspartate-semialdehyde dehydrogenase) inhibitor.
Is L-cysteine good for hair growth?

What kind of stones are made of cystine?
