| Common Name | (R)-pantoate |
|---|
| Description | (r)-pantoate, also known as (R)-pantoic acid, is a member of the class of compounds known as hydroxy fatty acids. Hydroxy fatty acids are fatty acids in which the chain bears a hydroxyl group (r)-pantoate is soluble (in water) and a weakly acidic compound (based on its pKa). (r)-pantoate can be found in a number of food items such as spinach, gooseberry, chanterelle, and walnut, which makes (r)-pantoate a potential biomarker for the consumption of these food products. |
