Common Name | (22E,24R)-Stigmasta-4,22-diene-3,6-dione |
---|
Description | (22E,24R)-Stigmasta-4,22-diene-3,6-dione is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, (22E,24R)-stigmasta-4,22-diene-3,6-dione has been detected, but not quantified in, a few different foods, such as fruits, pulses, and soy beans. This could make (22E,24R)-stigmasta-4,22-diene-3,6-dione a potential biomarker for the consumption of these foods. |
