Solution
The correct option is E Concanavalin A
Concanavalin A (ConA) is a lectin (carbohydrate-binding protein) originally extracted from the jack-bean, Canavalia ensiformis. It is a member of the legume lectin family. It binds specifically to certain structures found in various sugars, glycoproteins and glycolipids, mainly internal and non-reducing terminal -D-mannosyl and -D-glucosyl groups. ConA is a plant mitogen and is known for its ability to stimulate mouse T-cell subsets giving rise to four functionally distinct T cell populations, including precursors to suppressor T-cell. Diterpene, a type of terpene, is an organic compound composed of four isoprene units. Curcumin is a substance in turmeric and morphine is an analgesic opioid drug. Thus, the correct answer is option D.
