Common Name | Apo-13-zeaxanthinone |
---|
Description | Apo-13-zeaxanthinone is a member of the class of compounds known as sesquiterpenoids. Sesquiterpenoids are terpenes with three consecutive isoprene units. Apo-13-zeaxanthinone is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Apo-13-zeaxanthinone can be found in a number of food items such as red bell pepper, italian sweet red pepper, pepper (c. annuum), and orange bell pepper, which makes apo-13-zeaxanthinone a potential biomarker for the consumption of these food products. |
