El aminofosfonato ácido aminometilfosfónico (AMPA) es un ácido orgánico débil con un grupo fosfonato. Es uno de los principales productos de degradación del herbicida glifosato.^[2] El AMPA tiene baja toxicidad, que es comparable a la del glifosato.^[3] Se ha encontrado que puede ser descompuesto de manera natural en el suelo^[4] o transformado en ácido fosfórico mediante la acción bacteriana^[5]^[6] y finalmente a dióxido de carbono y fosfato inorgánico.^[7]
