BiosynthesisofTryptophaninBacteriaandPlants
The aromatic amino acid tryptophan is an essential nutrient, meaning that humans and animals do not themselves have the biosynthetic machinery to synthesize tryptophan but rely on dietary intake from bacteria and plants that do produce it. Tryptophan serves not only as a building block for protein synthesis but a precursor for synthesis of serotonin (see Neurotransmitter biosynthesis pathway). The tryptophan biosynth......阅读全文
