Cannabis Compound Identification
Common NameL-Tyrosine
DescriptionTyrosine or L-tyrosine abbreviated Tyr or Y, is a non-essential, hydrophobic amino acid synthesized from phenylalanine, which is derived from food. In humans, the enzyme phenylalanine hydroxylase catalyzes the conversion of phenylalanine to tyrosine. Tyrosine is strong basic compound with an odorless taste. Tyrosine is found in highest concentrations in protein rich foods such as caseins (cheese, yogurt), milk (cow), chicken, turkey, peanuts, almonds, sesame seeds, lima beans and soy products and in lower concentrations in avocado, bananas, semolina, crayfish, and crabs. Tyrosine has also been detected in annual wild rices, lovages, corianders, lumpsuckers, and sugars making tyrosine a potential biomarker for the consumption of these foods. Tyrosine is also found in cannabis plants (PMID: 6991645 ). It is not found in high concentrations in the body as it is rapidly metabolized. Valine and other branched amino acids, and possibly tryptophan and phenylalanine may reduce tyrosine absorption. Tyrosine readily passes the blood-brain barrier where it is converted to L-dopamine (L-dopa) by tyrosine hydroxylase. L-dopa is a precursor of the catecholamines, norepinephrine and epinephrine. L-dopa is used to treat Parkinson's (PMID: 29503325 ) and tyrosine, in large doses, can be used as an adjunct in the treatment of Parkinson's. Tyrosine is also the precursor for the thyroid hormones (PMID: 29892819 ) and for the human pigment, melanin. Tyrosine is an important amino acid in many proteins, peptides and even enkephalins, the body's natural pain reliever. The hydroxyl of tyrosine can be phosphorylated by protein kinases (PMID: 10966463 ), creating phosphotyrosine. This phosphorylation is an important part of signal transduction within the cell and also alters the enzymatic activity of target proteins. There are several genetic errors of tyrosine metabolism such as hawkinsinuria and tyrosinemia I (PMID: 30740402 ) where there is an increased amount of tyrosine in the blood of premature infants. This causes decreased motor activity, lethargy, poor feeding, infection and intellectual deficits. Vitamin C supplements may reverse the disease as increasing amounts of vitamin C improved performance in chicks supplemented with excess tyrosine (PMID: 7104784 ). Some adults also develop elevated tyrosine in their blood signaling a need for more vitamin C. More tyrosine is needed under stress, and tyrosine supplements may prevent the stress-induced depletion of norepinephrine and can cure biochemical depression. However, excess, tyrosine may lead to psychosis. Indeed, many antipsychotic medications apparently function by inhibiting tyrosine metabolism. L-Tyrosine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Gene Name:
GOT1
Uniprot ID:
P17174
Molecular weight:
46247.14
General function:
Involved in transferase activity, transferring nitrogenous groups
Specific function:
Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). Plays a key role in amino acid metabolism. Important for metabolite exchange between mitochondria and cytosol. Facilitates cellular uptake of long-chain free fatty acids.
Gene Name:
GOT2
Uniprot ID:
P00505
Molecular weight:
47517.285
General function:
Involved in nucleotide binding
Specific function:
Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two-step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr) (By similarity).
