| Common Name | 5-Hydroxy-4-pentenoic acid d-lactone |
|---|
| Description | 5-Hydroxy-4-pentenoic acid d-lactone belongs to the class of organic compounds known as dihydropyranones. Dihydropyranones are compounds containing a hydrogenated pyran ring which bears a ketone, and contains one double bond. 5-Hydroxy-4-pentenoic acid d-lactone has been detected, but not quantified in, nuts. This could make 5-hydroxy-4-pentenoic acid D-lactone a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 5-Hydroxy-4-pentenoic acid d-lactone. |
