Microcystins (also known as cyanoginosins) are a class of toxins produced by certain freshwater cyanobacteria. 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."}]
