Phenylalanine metabolismMorphologyAnthocyaninMelatonin is a kind of multifunctional hormone, analogous to indoleacetic acid in structure. To uncover the relationship between exogenous melatonin and the phenylalanine pathway, the liquid chromatography mass spectrometry (LCMS) was performed to quantify endogenous ...
Phenylalanine arises from an enzyme defect of phenylalanine metabolism. Under normal conditions, phenylalanine is converted to tyrosine by phenylalanine hydroxylase (PAH) after consumption of protein. Patients diagnosed with phenylketonuria (PKU) have a defect in PAH, and thus cannot hydroxylate ...
As the key rate-limiting enzyme in the phenylpropane metab- olism pathway, Phenylalanine ammonia-lyase (PAL; EC4.3.1.5) catalyzes the deamination of L-phenylalanine to produce trans-cinnamic acid [2, 3]. PAL is the first-rate limiting enzyme for phenylpropanoid metabolism, which regulates the ...
In plants, biosynthesis of phenylalanine occurs via two alternative pathways, both requiring conversion of chorismate, the final product of the shikimate pathway, to prephenate by chorismate mutase. Genetic studies showed that out of the two pathways the major carbon flux is directed through the aroge...
Two out of three aromatic amino acids, L-tyrosine and L-tryptophan, are precursors from the primary metabolism which retain — predominantly via the corresponding biogenic amine — their principal C- and N-skeleton in the pathway-specific biosynthesis of many classes of alkaloids in the plant ...
Effect of Phenylalanine-free Diet on Phenylalanine Metabolism in the Adult RoosterThis experiment was conducted to confirm the reason why roosters adapt themselves to a phenylalanine(Phe)-free diet. The results that recovery % of 14C of injected dl-Phe-2-14C in expired air reduced drastically for...

Phenylalanine Metabolism The levels of l-phenylalanine, phenylpyruvic acid, phenyllac- tic acid, and ortho-hydroxyphenylacetic acid, which belong to the phenylalanine metabolism pathway, in the hair were measured and found to be significantly different between Aβ1-42-induced rats and sham rats. ...
