Metabolite Identification
Common Name16-oxo-palmitate
Description16-oxo-palmitate is also known as 16-oxo-hexadecanoate. 16-oxo-palmitate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 16-oxo-palmitate can be found in a number of food items such as garden rhubarb, japanese pumpkin, carrot, and soy bean, which makes 16-oxo-palmitate a potential biomarker for the consumption of these food products.
