Amino Acids (Urine) by The Great Plains Laboratory
Alpha-amino-N-butyrateOptimal range: 5 - 72 qM/g creatinine
Alpha amniobutyric acid (AABA), also known as Alpha-amino-N-butyric acid (A-ANB), is an intermediate formed during the catabolism of methionine and threonine. Increases in AABA occur secondary to elevations of either methionine or threonine. AABA becomes propionic acid via alpha-ketobutyric acid in the presence of adequate amounts of thiamin, vitamin B2(as FAD), vitamin B3(as NAD), lipoic acid and magnesium. Deficiencies of any of these, or vitamin B6, could cause increases in AABA. Elevated or decreased levels of the amino acid may indicate a congenital enzyme defect.LEARN MORE
Alpha-aminoadipateOptimal range: 6 - 72 qM/g creatinine
Alpha-aminoadipic acid (a-Aminoadipic acid) is an intermediary metabolite of lysine (primarily) and of tryptophan.LEARN MORE
CreatinineOptimal range: 30 - 225 mg/dL
The urinary creatinine concentration (CC) represents the actual creatinine concentration in the specimen that was submitted.
Under normal conditions, the rate of excretion of creatinine is quite constant and highly correlated with lean body mass (muscle). However, the CC can vary significantly as a function of urine volume.LEARN MORE
Gamma-aminobutyrateOptimal range: 0 - 7 qM/g creatinine
Gamma-aminobutyrate (GABA) is the major inhibitory neurotransmitter found in the CNS and, as such, is important for balancing excitatory action of other neurotransmitters.LEARN MORE
HydroxyprolineOptimal range: 0 - 45 qM/g creatinine
Hydroxyproline is a collagen related amino acid. Hydroxyproline is a nonessential amino acid, which means that it is manufactured from other amino acids in the liver. Hydroxyproline is necessary for the construction of the body’s major structural protein, collagen. Hydroxyproline is present in essentially all tissues and all genetic types of collagen.LEARN MORE
TyrosineOptimal range: 28 - 120 qM/g creatinine
Tyrosin is the non-essential amino acid precursor for dopamine, norepinephrine and epinephrine. Tyrosine hydroxylase converts tyrosine into the dopamine precursor L-DOPA; BH4, Vitamin D and iron are cofactors for that enzymatic activity.
Tyrosine enhances cognitive performance, energy, and alertness, and improves memory after sleep deprivation.LEARN MORE
