What are the function of terpenoids?

Terpenes and derived terpenoids, also known as isoprenoids, are the largest class of plant secondary metabolites, with basic functions in growth and development, and more specialized roles in plantenvironment interactions, resistance/tolerance to environmental stresses, and defence against predators and pathogens.

What are terpenoids in plants?

Abstract. Terpenoids are the largest group of plant specialized (secondary) metabolites. These naturally occurring chemical compounds are highly diverse in chemical structure. Although there have been many excellent studies of terpenoids, most have focused on compounds built solely of isoprene units.
