A chemical related to adrenaline and dopamine. It occurs naturally in the body and in the form levodopa is used to treat Parkinson’s disease.
A physiologically important compound that forms an intermediate stage in the synthesis of catecholamines (dopamine, epinephrine, and norepinephrine) from the essential amino acid tyrosine. It also plays a role itself in the functioning of certain parts of the brain. The form L dopa is administered for the treatment of parkinsonism, a disease in which there is a deficiency of dopamine in the brain.
A precursor of dopamine and noradrenaline. Levodopa is a drug used in the treatment of parkinsonism. It can cross the blood-brain barrier and increase the concentration of dopamine in the basal ganglia. It also inhibits prolactin secretion and may be used to treat galactorrhea.
A chemical substance, 3,4-dihydroxyphenylalanine, produced by the oxidation of tyrosine to tyrosinase. It is a precursor of catecholamines and melanin.
In the realm of biological processes, there exists a widely recognized term to denote a naturally occurring compound known as 3, 4-dihydroxyphenylalanine. This chemical substance, synthesized within the human body, plays a pivotal role in the intricate procedure of melanin synthesis.
An amino acid utilized by the body to generate dopamine, a crucial neurotransmitter. Dopa is also produced as an intermediate step in the body’s creation of epinephrine, norepinephrine, and melanin. Levodopa, a variant of dopa, is used to compensate for a dopamine deficiency in individuals with Parkinson’s disease.
