Microcystin-LR (MC-LR) is a toxin produced by cyanobacteria. It is the most toxic of the microcystins.
==Structure== Microcystins are cyclic heptapeptides. The seven amino acids that are involved in the structure of a microcystin include the unique amino acids ADDA and D-β-methyl-isoaspartate (D-β-Me-isoAsp). Furthermore, microcystins contain two variable residues, which make the differentiation between variants of microcystins. These two variable functionalities are always standard proteinogenic amino acids - In microcystin-LR these are leucine and arginine.
