Antioxidants
Naturally occurring or synthetic substances that inhibit or retard oxidation reactions. They counteract the damaging effects of oxidation in animal tissues. (See all compounds classified as Antioxidants.)
Food Preservatives
Substances capable of inhibiting, retarding or arresting the process of fermentation, acidification or other deterioration of foods. (See all compounds classified as Food Preservatives.)
Anti-Infective Agents
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection. (See all compounds classified as Anti-Infective Agents.)
Serine Proteinase Inhibitors
Exogenous or endogenous compounds which inhibit SERINE ENDOPEPTIDASES. (See all compounds classified as Serine Proteinase Inhibitors.)
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)
