picture info	L-DOPA -DOPA, also known as levodopa and -3,4-dihydroxyphenylalanine, is an amino acid that is made and used as part of the normal biology of some plants and animals, including humans. Humans, as well as a portion of the other animals that utilize -DOPA, make it via biosynthesis from the amino acid -tyrosine. -DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. Furthermore, -DOPA itself mediates neurotrophic factor release by the brain and CNS. -DOPA can be manufactured and in its pure form is sold as a psychoactive drug with the INN levodopa; trade names include Sinemet, Pharmacopa, Atamet, and Stalevo. As a drug, it is used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia. -DOPA has a counterpart with opposite chirality, -DOPA. As is true for many molecules, the human body produces only one of these isomers (the -DOPA form). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	D-DOPA -DOPA (-3,4-dihydroxyphenylalanine; dextrodopa) is similar to -DOPA (levodopa), but with opposite chirality. Levo- and dextro- rotation refer to a molecule's ability to rotate planes of polarized light in one or the other direction. Whereas -DOPA is moderately effective in the treatment of Parkinson's disease (PD) and dopamine-responsive dystonia (DRD) by stimulating the production of dopamine in the brain, -DOPA is biologically inactive. See also * -DOPA (Levodopa; Sinemet, Parcopa, Atamet, Stalevo, Madopar, Prolopa, etc.) * -DOPS (Droxidopa) * Methyldopa (Aldomet, Apo-Methyldopa, Dopamet, Novomedopa, etc.) * Dopamine (Intropan, Inovan, Revivan, Rivimine, Dopastat, Dynatra, etc.) * Norepinephrine (Noradrenaline; Levophed, etc.) * Epinephrine Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	3,4-Dihydroxyphenylacetic Acid 3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. Dopamine can be metabolized into one of three substances. One such substance is DOPAC. Another is 3-methoxytyramine (3-MT). Both of these substances are degraded to form homovanillic acid (HVA). Both degradations involve the enzymes monoamine oxidase (MAO) and catechol-O-methyl transferase (COMT), albeit in reverse order: MAO catalyzes dopamine to DOPAC, and COMT catalyzes DOPAC to HVA; whereas COMT catalyzes dopamine to 3-MT and MAO catalyzes 3-MT to HVA. The third metabolic end-product of dopamine is norepinephrine (noradrenaline). DOPAC can be oxidized by hydrogen peroxide, leading to the formation of toxic metabolites which destroy dopamine storage vesicles in the substantia nigra. This may contribute to the failure of levodopa treatment of Parkinson's disease. A MAO-B inhibitor such as selegiline or rasagiline can prevent this from happening. It can also be found in the bark o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Deleting Online Predators Act Of 2006 The Deleting Online Predators Act of 2006"http://thomas.loc.gov/cgi-bin/query/z?c109:H.R.5319:" (DOPA) is a bill (H.R. 5319) brought before the United States House of Representatives on May 9, 2006 by Republican Pennsylvania Representative (R-PA) Mike Fitzpatrick. The bill, if enacted, would have amended the Communications Act of 1934, requiring schools and libraries that receive E-rate funding to protect minors from online predators in the absence of parental supervision when using "Commercial Social Networking Websites" and "Chat Rooms". The bill would prohibit schools and libraries from providing access to these types of websites to minors or create restrictions to use of these type of sites. The bill also would require the institutions to be capable of disabling the restrictions for "use by an adult or by minors with adult supervision to enable access for educational purposes." After passing the House, it was sent to the Senate and referred to committee in July 2006. It was re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
