WebPhenylalanine is the end product of the shikimate pathway and links primary metabolism with the phenylpropanoid, flavonoid, and anthocyanin secondary metabolism pathways. This pathway is found in microorganisms and plants, but not in animals [84]. WebPhenylalanine hydroxylase: function, structure, and regulation Mammalian phenylalanine hydroxylase (PAH) catalyzes the rate-limiting step in the phenylalanine catabolism, consuming about 75% of the phenylalanine input from the diet and protein catabolism under physiological conditions.

WebBecause phenylalanine accumulates in tissues and plasma (hyperphenylalaninemia), it is metabolized by alternative pathways and abnormal amounts of phenylpyruvate appear in urine. Phenylalanine hydroxylase deficiency may be complete (classic PKU, type I) or partial (types II and III). WebTyrosine, phenylalanine and tryptophan are the three aromatic amino acids (AAA) involved in protein synthesis. These amino acids and their metabolism are linked to the synthesis of a variety of secondary metabolites, a subset of which are involved in numerous anabolic pathways responsible for the synthesis of pigment compounds, plant hormones and …
