Escherichia coli metabolite
Any bacterial metabolite produced during a metabolic reaction in Escherichia coli.
Saccharomyces cerevisiae metabolite
Any fungal metabolite produced during a metabolic reaction in Baker's yeast (Saccharomyces cerevisiae ).
human metabolite
Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
antagonist
Substance that attaches to and blocks cell receptors that normally bind naturally occurring substances.
mouse metabolite

food packaging gas
A food additive that is a (generally inert) gas which is used to envelop foodstuffs during packing and so protect them from unwanted chemical reactions such as food spoilage or oxidation during subsequent transport and storage. The term includes propellant gases, used to expel foods from a container.
food propellant
A propellant that is used to expel foods from an aerosol container.

refrigerant
A substance used in a thermodynamic heat pump cycle or refrigeration cycle that undergoes a phase change from a gas to a liquid and back. Refrigerants are used in air-conditioning systems and freezers or refrigerators and are assigned a "R" number (by ASHRAE - formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers), which is determined systematically according to their molecular structure.
solvent
A liquid that can dissolve other substances (solutes) without any change in their chemical composition.
vasodilator agent
A drug used to cause dilation of the blood vessels.
anaesthetic
Substance which produces loss of feeling or sensation.
