Biosynthesis of alkaloids in plants
WebAlkaloids represent a structurally diverse group of nitrogen-containing secondary metabolites. Many of them have pronounced pharmacological activities and are therefore important for medicine and biotechnology. Most alkaloids derive from an amino acid as a precursor, such as ornithine, arginine, lysine, phenylalanine, tyrosine or tryptophan.
