<span style="font-family:arial,helvetica,sans-serif;"><span style="font-size:12px;">L-<wbr />(+)-<wbr />Cystathionine (CAS 56-88-2)&nbsp;is a dipeptide formed by serine and homocysteine. Transsulfuration of methionine yields homocysteine, which combines with serine to form this precursor of cysteine. L-<wbr />(+)-<wbr />Cystathionine is largely expressed in the mammalian brain and deficiency can indicate the presence of metabolic disorders such as cystathioninuria.</span></span>
