Natural Product Identification
Common NamePurothionin AII
DescriptionPurothionin AII, also known as blastmycin or a1-purothionin, belongs to the class of organic compounds known as acylaminobenzoic acid and derivatives. These are derivatives of amino benzoic acid derivatives where the amine group is N-acylated. Purothionin AII is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Purothionin AII has been detected, but not quantified in, a few different foods, such as cereals and cereal products, common wheats, and wheats. Purothionin AII is found in Streptomyces argillaceus. This could make purothionin aii a potential biomarker for the consumption of these foods.
