Terpenoids are organic chemicals that produce naturally by many plants and are derived from terpenes. This provides plants their own distinct aroma including the cannabis. Widely used terpenoids are the cannabinoids found in cannabis, the curcuminoids found in turmeric and salvinorin A in the plant Salvia divinorum. Hence the steroids in plants are biologically produced from terpenoid precursors and sometimes they can be added to proteins to enhance their attachment to the cell membrane.
