Metabolite Identification
Common Name1-Pyrroline
Description1-Pyrroline belongs to the class of organic compounds known as pyrrolines. Pyrrolines are compounds containing a pyrroline ring, which is a five-member unsaturated aliphatic ring with one nitrogen atom and four carbon atoms. 1-Pyrroline exists in all living organisms, ranging from bacteria to humans. In humans, 1-pyrroline is involved in the metabolic disorder called hyperornithinemia with gyrate atrophy (hoga). 1-Pyrroline is an ammoniacal and shrimp tasting compound. 1-Pyrroline is found, on average, in the highest concentration within grape wine. 1-Pyrroline has also been detected, but not quantified in, several different foods, such as cottonseeds (Gossypium), cauliflowers (Brassica oleracea var. botrytis), jew's ears (Auricularia auricula-judae), menthas (Mentha), and common hazelnuts (Corylus avellana). This could make 1-pyrroline a potential biomarker for the consumption of these foods. 1-Pyrroline is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 1-Pyrroline.
