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

Phosphorylation with loss of CO2 and phosphate ion completes synthesis

Isopentyl pyrophosphate is _______with 2-methylallyl pyrophosphate

Geranyl pyrophosphate with one molcules of isopentyl pyrophosphatein the same manner mention previously will give ( _____) atom compound called farnesyl pyrophosphate

10C to 15C then _____ Fpp with the presence of NADPH will give Squalene which direct precursor for steroidal nucleus.
