Trostruki heliks

U geometriji, trostruki heliks je set od tri kongruentna geometrijska heliksa sa zajedničkom osom, koji se razlikuju po translaciji dužose. Primeri strukture u obliku trostrukog heliksa su:

kolagenski heliks^[1]
peptido nukleinska kiselina (neki tipovi)^[2]
Trolančana DNK^[3]^[4]
