What fat-soluble substance is converted to dopamine in the brain?

Dopamine functions as a neurotransmitter activating dopamine receptors, and is essential to the normal functioning of the central nervous system.
Dopamine has many functions, the most important being the central reward system (mesolimbic brain) and in controlling and coordinating movement.
It is produced from L-tyrosine, a non-essential amino acid, which is converted into L-DOPA by the enzyme tyrosine hydroxylase. L-DOPA is then converted to dopamine by the enzyme DOPA decarboxylase.
L-DOPA is the precursor to dopamine and is given as medication to people suffering from diseases such as Parkinson's Disease because, unlike dopamine, L-DOPA is more fat-soluble, and, as such, can cross the blood-brain barrier.

Which substance has a chemical composition similar enough to dopamine to allow it to fit the dopamine receptor sites in the brain?
all
What substance is produced and released by neurons in the brain?
The substance that is produced and released by neurons in the brain is a hormone called dopamine. It acts as a neurotransmitter that sends signals between nerve cells.
How much Dopamine is in an average person's brain?
The range of dopamine in the brain that is considered 'normal' is from 70mcg to 350mcg.
Does alcohol affect the dopamine gland?
Dopamine is produced by nerve cells in the brain. There is no dopamine gland.
The neurotransmitter dopamine is involved in?
Dopamine is involved in the brain's reward and pleasure centers.
How does a substance such as Methamphetamines produce its effects?
The "substance" binds itself to the dopamine receptors and tricks the brain into believing it is receiving messages from dopamine.

How does nicotine influence dopamine receptors in the brain?
Increasing release of dopamine
Which system is effected by pakinson's disease?
Parkinson's disease is a condition which affects the part of the brain, called the substantia Niagara . Normally this part of the brain inhibits the excessive movement in the body by releasing an substance called dopamine into the rest of the brain. Loss of this will cause the disturbed movements and other symptoms seen in parkinsonism. That is why drugs which increases the dopamine in the brain is given to treat this condition.
The neurotransmitter dopamine is involved in?
Dopamine is involved in the brain's reward and pleasure centers.
Is sinemet an maoi drug?
No. Sinemet is a combination of a prodrug (levodopa, which is converted in the body to dopamine) and an inhibitor that prevents the conversion (the enzyme it inhibits is DOPA decarboxylase; MAOI drugs inhibit monoamine oxidase). The inhibitor is highly polar and cannot pass the blood-brain barrier, so it inhibits the conversion of levodopa to dopamine in the body generally, but allows conversion within the brain. This is done because high levels of dopamine outside the brain can result in nausea and vomiting.
What are dopamine receptor agonists?
Dopamine receptor agonists are a class of drugs with similar actions to dopamine, a neurotransmitter that occurs naturally in the brain.
What hormone produces the brain?
dopamine and serotonin are some brain homones
