L,L-Dityrosine (o,o'-Dityrosine) is a constituent of acid hydrolysates of a number of biological materials, including the insect cuticular resilin[1]. | [Definition]
ChEBI: LL-dityrosine is a dityrosine. It is an enantiomer of a DD-dityrosine. | [in vivo]
L,L-Dityrosine (o,o'-Dityrosine) is elevated in ventral midbrain and striatum of MPTP-treated mice[2]. | [References]
