Arsenobetain adalah senyawa organoarsen yang banyak ditemukan pada ikan.[1][2][3][4] Arsen ini analog dengan trimetilglisin, yang umum dikenal sebagai betaine. Biokimia dan biosintesis betain mirip dengan kolin.
Arsenobetain adalah senyawa umum dalam sistem biologi laut dan tidak seperti kebanyakan senyawa organoarsen seperti dimetilarsin dan trimetilarsin, arsenobetain relatif tidak beracun.[5]
Sejak tahun 1920 telah diketahui bahwa ikan laut mengandung senyawa organoarsen, tetapi baru tahun 1977 struktur kimia senyawa yang paling melimpah, arsenobetain, ditemukan.[6]
