WebIn phenylketonuria (PKU), there is an inability to metabolise dietary phenylalanine (Phe) into tyrosine (Tyr) due to a deficiency of Phe hydroxylase. It is treated by a low Phe diet, and the major source of protein equivalent is provided by a Phe-free or low Phe protein substitute, in the form of either l -amino acids ( l -AA) or casein glycomacropeptide (CGMP-AA).

WebThe phenylalanine-to-tyrosine ratio (Phe/Tyr) has been proposed as an estimate of BH 4 levels , because phenylalanine and tyrosine can be regarded as more stable analytes than BH 4. Serum concentrations of phenylalanine and tyrosine are in the range of 53–79 and 61–116 µmol/L, respectively [ 44 ]. WebDec 27, 2024 · The amino acids most used as alternative respiratory substrates belong to a moderately costly group (proline, glutamate, branched-chain amino acids [BCAAs]) (Arnold et al., 2015; Figure 3), while high-cost amino acids such as arginine, histidine, tyrosine, tryptophan, and phenylalanine generally serve as precursors for secondary metabolites ...
