L-Cysteinyl-L-tyrosine is a dipeptide consisting of L-cysteine and L-tyrosine. L-cysteine is a sulfur-containing amino acid involved in antioxidant defense and the formation of disulfide bonds in proteins, while L-tyrosine is an aromatic amino acid important for synthesizing neurotransmitters like dopamine and norepinephrine. This dipeptide might be studied for its potential effects on oxidative stress, neurochemistry, and protein stability, combining the antioxidant properties of cysteine with the neurotransmitter-related functions of tyrosine.
