Metabolite Identification

Common Name

Monoethyl malonic acid

Description

Monoethyl malonic acid, also known as (ethoxycarbonyl)acetate or 3-ethoxy-3-oxopropanoate, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Monoethyl malonic acid has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make monoethyl malonic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Monoethyl malonic acid.
