BIOSYNTHESIS

'Biosynthesis' is a phenomenon where chemical compounds are produced from simpler reagents. Biosynthesis, unlike chemical synthesis, takes place within living organisms and is generally catalysed by enzymes. The process is a vital part of metabolism.
The prerequisites for biosynthesis are:

★ Precursor substances

★ Energy (usually in the form of ATP)
Often required components include:

★ Catalysts, usually enzymes

★ Reduction equivalents (in the form of NADH, NADPH and others)
Important and commonly known products of biosynthesis include proteins, vitamins, and antibiotics, but all components of living beings are a result of this process. In the near future it may be possible, with the help of biotechnology, to harness this process for the production of biodegradable plastics.
