Dictionary > Biosynthesis


The production of a complex chemical compound from simpler precursors in a living organism, usually involving enzymes (to catalyze the reaction) and energy source (such as ATP)
The creation of an organic compound in a living organism is referred to as biosynthesis. Biosynthesis refers to the production of a complex chemical compound from simpler precursors in a living organism. It is usually involving enzymes that will catalyze the reaction) and energy source (e.g. ATP). Examples of biosynthesis include photosynthesis, chemosynthesis, amino acid synthesis, nucleic acid synthesis, and ATP synthesis. In particular, photosynthesis is the synthesis of complex organic material using carbon dioxide, water, inorganic salts, and light energy (from sunlight) captured by light-absorbing pigments, such as chlorophyll and other accessory pigments. Chemosynthesis is the synthesis of a biological compound (e.g. carbohydrates). Amino acid synthesis is the synthesis of an amino acid, which in turn is used in the synthesis of proteins and peptides. Nucleic acid synthesis is the biosynthesis of nucleic acids, such as DNA and RNA. ATP synthesis is the synthesis of ATP, which is a source of biological energy in cells.
Word origin: bio– (“life”) + Greek sunthesis, from suntithenai (“to put together”)
