Identification
Name: Crotonobetaine
Description:Crotonobetaine is a member of the chemical class known as Quaternary Ammonium Salts. These are compounds containing positively charged polyatomic ion of the structure NR4+, R being an alkyl group or an aryl groupCrotonobetaine is invovled in Carnitine metabolism, and ABC transporters. Crotonobetaine is involved in carnitine metabolism. Carnitine dehydratase from Pseudomonas aeruginosa O44 K74 is an inducible enzyme detectable in cells grown anaerobically in the presence of L-(-)-carnitine or crotonobetaine. (PMID 8188598).
