Microcystins have a common structural framework of D-Ala 1-X 2-D-Masp 3-Z 4-Adda 5-D-γ-Glu 6-Mdha 7, where X and Z are variable amino acids; the systematic name "microcystin-XZ" (MC-XZ in short) is then assigned based on the one letter codes (if available; longer codes otherwise) of the amino acids.
