Squalene is
biosynthesised by
coupling two
molecules of
farnesyl pyrophosphate. The condensation...

reverse the
reaction in
which chlorophylls are
biosynthesised from
chlorophyllide a or b.
Since chlorophyllide a can be converted...

Steroids feature a
cucurbitane core,
although in
practice they are
biosynthesised from
either lanosterol (animals and fungi) or
cycloartenol (plants)...

Ammonia plays a role in both
normal and
abnormal animal physiology. It is
biosynthesised through normal amino acid
metabolism and is
toxic in high concentrations...

treat several types of cancers, are
found in the
plant and are
biosynthesised from the
coupling of the
alkaloids catharanthine and vindoline. The...

Sclerotinia sclerotiorum cause a

besides being biosynthesised, may also be biodegraded.
Oxalobacter formigenes is an
