dihydroxyphenylalanine and Clasp-Knife Spasticity

dihydroxyphenylalanine has been researched along with Clasp-Knife Spasticity in 2 studies

Dihydroxyphenylalanine: A beta-hydroxylated derivative of phenylalanine. The D-form of dihydroxyphenylalanine has less physiologic activity than the L-form and is commonly used experimentally to determine whether the pharmacological effects of LEVODOPA are stereospecific.
dopa : A hydroxyphenylalanine carrying hydroxy substituents at positions 3 and 4 of the benzene ring.
