Toxic levels of phenylalanine, along with insufficient levels of tyrosine, can interfere with infant development in ways that have permanent effects. The disease may present clinically with seizures , hypopigmentation (excessively fair hair and skin), and a "musty odor" to the baby's sweat and urine (due to phenylacetate , a carboxylic acid ...
D-Phenylalanine (DPA, D-Phe), sold under the brand names Deprenon, Sabiben, and Sabiden, is an enantiomer of phenylalanine which is described as an antidepressant and is marketed as a prescription drug for medical use in Argentina. [1] [2] The medication has been marketed since at least the 1970s [3] and continued to be available by the 2000s. [1]
D-Phenylalanine is distributed to the various tissues of the body via the systemic circulation. It appears to cross the blood–brain barrier less efficiently than L-phenylalanine, and so a small amount of an ingested dose of D-phenylalanine is excreted in the urine without penetrating the central nervous system. [24] L-Phenylalanine is an ...
Standard phenylalanine concentrations in unaffected persons are about 2-6mg/dl (120–360 μmol/L) phenylalanine concentrations in those with untreated hyperphenylalaninemia can be up to 20 mg/dL (1200 μmol/L). Measurable IQ deficits are often detected as phenylalanine levels approach 10 mg/dL (600 mol/L).
3. Medications. Some medications have been associated with temporary hair loss. Most of the time hair loss related to medication is due to the drug disrupting the hair growth cycle leading to a ...
Tetrahydrobiopterin deficiency (THBD, BH 4 D) is a rare metabolic disorder that increases the blood levels of phenylalanine.Phenylalanine is an amino acid obtained normally through the diet, but can be harmful if excess levels build up, causing intellectual disability and other serious health problems.
Adderall and Mydayis [11] are trade names [note 2] for a combination drug containing four salts of amphetamine.The mixture is composed of equal parts racemic amphetamine and dextroamphetamine, which produces a (3:1) ratio between dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine.

It has been used experimentally to treat carcinoid syndrome, but the side effects, mostly hypersensitivity reactions and psychiatric disturbances, have prevented development for this use. [ 3 ] The effects of serotonin depletion from fenclonine are so drastic that serotonin cannot even be detected immunohistochemically within the first day ...
