Roles Classification
Chemical Role(s): antioxidant
A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
Biological Role(s): animal metabolite
Any eukaryotic metabolite produced during a metabolic reaction in animals that include diverse creatures from sponges, insects to mammals.
food colouring
A food additive that imparts colour to food. In European countries, E-numbers for permitted food colours are from E 100 to E 199, divided into yellows (E 100-109), oranges (E 110-119), reds (E 120-129), blues and violets (E 130-139), greens (E 140-149), browns and blacks (E 150-159), and others (E 160-199).
plant metabolite
Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
Application(s): anticoagulant
An agent that prevents blood clotting.
