Its exact synthesis pathway from farnesyl pyrophosphate is still unknown.
Production is also limited by feedback in the synthesis pathway of penicillin.
Increased levels of acetyl-CoA will increase the flux through not only the fat synthesis pathway but also the citric acid cycle.
Examples include (in order of synthesis pathway):
In the terminal-tryptophan synthesis pathway, the initial step converts chorismate to anthranilate using anthranilate synthase.
Inosinate is the first intermediate in this synthesis pathway to have a whole purine ring.
The endogenous production of insulin is regulated in several steps along the synthesis pathway:
Through several steps taking place is both the cytosol and endoplasmic reticulum, the synthesis pathway yields the end product of PE.
Addition reactions are inherently atom efficient, so are preferred synthesis pathways.
Amino acids must be synthesized from glucose by a group of specialized enzymes; the synthesis pathways are arbitrary and conserved.
