MeSH Heading: Dihydroxyphenylalanine
Tree Number(s): D02.092.311.200; D02.455.426.559.389.657.166.175.200; D12.125.072.050.685.400; D12.125.072.050.875.130
Unique ID: D004295
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D004295
Annotation: check text to see if LEVODOPA; (L-DOPA); is not meant instead
Scope Note: 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.
