The shikimate biosynthesis pathway provides precursors for aromatic molecules in bacteria, fungi, and plants

This biochemical pathway is a major link between primary and secondary metabolism in higher plants

The shikimate pathway produces
( aromatic amino acids)
L-phenylalanine , L- tyrosine , and L-tryptophan , molecular building blocks for protein biosynthesis.

in plants, these aromatic amino acids are only crucial components of protein biosynthesis

serve as precursors for diverse secondary metabolites that are important for _____

The principal aromatic phenolic compounds synthesized from L-Phe and L- Tyr are cinnamic acids and esters, coumarins, phenylpropenes, chromones (C6-C3), stilbenes,etc

____is a precursor of alkaloids in the secondary metabolism.

Through Shikimic acid pathway a series of phosphorylated intermediate yield chorismic acid

chorismic acid which is an important branch –point intermediate .

Acetic acid is the starting unit in the biosynthesis of a wide variety of straight chain and aromatic natural compounds

Acetate-Mevalonic acid pathway
It begins with conversion of acetate to

yields acetoacetyl Co A

———-claisen condensation reaction with third molecule of acetyl CoA yields six carbon compound 3-hydroxy-3-methylglutaryl CoA

3-hydroxy-3-methylglutaryl CoA is reduced to mevalonate
