carbon longer than alanine,
hence the
prefix homo-.
Homoalanine is
biosynthesised by
transaminating oxobutyrate, a
metabolite in
isoleucine biosynthesis...

Steroids feature a
cucurbitane core,
although in
practice they are
biosynthesised from
either lanosterol (animals and fungi) or
cycloartenol (plants)...
- most eukaryotes,
though has not been
found in Archaea.
Squalene is
biosynthesised by
coupling two
molecules of
farnesyl pyrophosphate. The condensation...
-
phytyl sidechain to
reverse the
reaction in
which chlorophylls are
biosynthesised from
chlorophyllide a or b.
Since chlorophyllide a can be converted...
- used to
treat several types of cancers, are
found in the
plant and are
biosynthesised from the
coupling of the
alkaloids catharanthine and vindoline. The...
- bear much or any
biological significance. For example,
histamine is
biosynthesised strictly via the
enzyme histidine decarboxylase in
humans and other...
-
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...
-
triiodothyronine (T3) and
thyroxine (T4) are aryl iodides. A tetraiodide, T4 is
biosynthesised by
electrophilic iodination of
tyrosine derivative.
Synthetic T4 is...

Chlorophyllide a
reductase (COR). Isobacteriochlorins, in contrast, are
biosynthesised from
uroporphyrinogen III in a
separate pathway that leads, for example...
- discovery, over 70 BR
compounds have been
isolated from plants. The BR is
biosynthesised from campesterol. The
biosynthetic pathway was
elucidated by ****anese...
