Metabolite Identification
Common NameN-Hexadecanoylpyrrolidine
DescriptionN-Hexadecanoylpyrrolidine belongs to the class of organic compounds known as n-acylpyrrolidines. These are n-Acylated Pyrrolidine derivatives. Pyrrolidine is a five-membered saturated aliphatic heterocycle with one nitrogen atom and four carbon atoms. N-Hexadecanoylpyrrolidine has been detected, but not quantified in, green vegetables and pepper (spice). This could make N-hexadecanoylpyrrolidine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on N-Hexadecanoylpyrrolidine.
