Sesquiterpenoids are terpenes with three consecutive isoprene units. Apo-11-zeaxanthinal is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Apo-11-zeaxanthinal can be found in a number of food items such as pepper (c. annuum), orange bell pepper, italian sweet red pepper, and red bell pepper, which makes apo-11-zeaxanthinal a potential biomarker for the consumption of these food products.
