Description
IUPAC distinguishes three definitions of 'substrate': (1) The chemical entity whose conversion to a product or products is catalysed by one or several enzymes. (2) A solution or dry mixture containing all ingredients which are necessary for the growth of a microbial culture or for product formation. (3) Component in the nutrient medium, supplying the organisms with carbon (C-substrate), nitrogen (N-substrate), etc.
A substrate in a chemical reaction has a negative stoichiometric number since it is consumed, whereas a product has a positive stoichiometric number since it is produced.
