It is one of a large family of microcystins. It is considered the most toxic compound of this family. Some evidence shows the toxin can be transported by irrigation into the food chain.  Microcystins are chemically stable over a wide range of temperature and pH, possibly as a result of their cyclic structure. The toxins are also resistant to enzymatic hydrolysis (in guts of animals) by some general proteases, such as pepsin, trypsin, collagenase, and chymotrypsin."}]
