Of or relating to the chemical reactions that occur in living organisms.
Any of a large number of chemical compounds made by a living system, composed commonly of carbon, hydrogen, oxygen, nitrogen, sulfur, and/or phosphorus (CHONSP).
Biochemical refers to the chemical reactions that occur within a living organism, such as the breakdown or manufacture of biological molecules by enzymes.
Characterized by, produced by, or involving chemical reactions in living organisms.
The study of the biological and chemical interactions of living things
Relating to biochemistry, the application of the tools and concepts of chemistry to living systems. See the entire definition of Biochemical
a product by or involving a chemical reaction in a living organism. Biochemistry is the application of chemistry to living beings. A few general research areas of biochemistry include analysis of the physical properties of biological molecules, the chemical interactions used to regulate metabolism, and the chemistry of the immune system.

A chemical that occurs naturally in an organism, or an identical substance that has been made artificially.
of or relating to biochemistry; involving chemical processes in living organisms
Substance concentration of oxygen taken up through the respiratory activity of micro-organisms growing on organic compounds present when incubated at a specified temperature (usually 20° C) for a fixed period (usually 5 days). It is regarded as a measure of that organic pollution of water which can be degraded biologically but includes the oxidation of inorganic material such as sulfide and iron(II). The empirical test used in the laboratory to determine BOD also measures the oxygen used to oxidize reduced forms of nitrogen unless their oxidation is prevented by an inhibitor such as allyl thiourea. RT chemical oxygen demand. Nagel et al. (eds), 1991
