A sikimisav útvonal jelentőségeThe shikimate pathway provides an alternative route to aromatic compounds,particularly the aromatic amino acids L-phenylalanine, L-tyrosine, and L-tryptophan. This pathway is employed by microorganisms and plants, butnot by animals; accordingly, the aromatic amino acids feature among theessential amino acids for man and have to be obtained in the diet.Phenylalanine and tyrosine form the basis of C 6 C 3 phenylpropaneunits found in many natural products, e.g. cinnamic acids,coumarins, lignans, and flavonoids, and along with tryptophan areprecursors of a wide range of alkaloid structures.
