Comparative Study of Two Sensors Performances Regarding the Detection of L-Phenylalanine and L-Tyrosine
Last modified: 2021-05-12
Abstract
Phenylalanine and Tyrosine are two important amino acids for the human body; there is an interdependent relationship between them. Phenylalanine is transformed into tyrosine and metabolized in the liver, but both amino acids are precursors for the neurotransmitters dopamine, adrenaline, and noradrenaline. Persons with high concentrations of phenylalanine in the body fluids may develop an inherited metabolic disease called phenylketonuria (PKU), and their bodies are unable to produce tyrosine. Following these considerations, the present paper describes the electroanalytical performances of two sensors observed by cyclic voltammetry for the detection of these two amino acids. The developed sensors demonstrated high performance characteristics, and can be successfully applied in the detection of the two amino acids in both human serum and drug supplements.
