ONKI3 | Medical Subject Headings

The ONKI is provided as a part of the ONKI Living Lab - an open lab for testing the latest semantic web technologies in practice, with real users like you. Currently, over 10 000 people are using ONKI each month.

We hope you like the ONKI service and enjoy using it for your purposes!

If you encounter any problems or have improvement ideas, please contact the ONKI team. We are also very much interested in your success stories in using ONKI - please share your experiences!

Scope note:	The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. X
