L-alpha-Aspartyl-L-valyl-L-prolyl-L-lysyl-L-seryl-L-alpha-aspartyl-L-glutaminyl-L-phenylalanyl-L-valylglycyl-L-leucyl-L-methioninamide

Kassinin Dodecapeptide tachykinin found in the central nervous system of the amphibian Kassina senegalensis. It is similar in structure and action to other tachykinins, but is especially effective in contracting smooth muscle tissue and stimulating the micturition reflex.

Molecular Formula: C₅₉H₉₅N₁₅O₁₈S
