Arsenobetaine is found in algae, lobsters, sharks, etc. Arsenobetaine is an organoarsenic compound that is the main source of arsenic found in fish. It is the arsenic analogue of trimethylglycine, commonly known as betaine. The biochemistry and its biosynthesis are similar to the biosynthesis of choline and betaine. The; Besides several other arsenic compounds, such as dimethylarsine and trimethylarsine, arsenobetaine is a common substance in the marine biological systems for arsenic detoxification."}]
