The main biosynthetic pathways of natural compounds:
1. Acetate-malonate pathway (AA-MA pathway)
Synthesis of fatty acids, phenols, Anthraquinones
2. Mevaleronate pathway (MVA pathway)
Mainly generates terpenes and steroidal compounds
3. Cinnamic acid pathway and shikimic acid pathway
Form compounds with C6-C3 skeleton, such as coumarin, lignans, flavonoids, etc.
4. Amino Acid Pathway
p>Synthetic alkaloids
5. Composite pathway
(1) Acetic acid-malonic acid-shikimic acid pathway
(2) Acetic acid- Malonic acid-meglutaric acid pathway
(3) Amino acid-meglutaric acid pathway
(4) Amino acid-acetate-malonic acid pathway
(5) Amino acid-shikimic acid pathway
