To realize Majorana fermions having novel physical features has been developed as a key while difficult task in topological superconductor. Here we have proposed another platform to generate Majorana zero modes (MZMs), which is constructed by a single opened circular helix molecules (CHM) coupled with a s-wave superconductor (with magnetic field) or by an interlinked-CHMs chain coupled with a phase-bias s-wave superconducting heterostructure (without any magnetic field). The MZMs achieved here are tightly associated with the structural chirality in CHMs. Importantly, the left and right handedness may result in completely opposite Majorana polarization (MP), and the local MP is associated to the chiraliy-induced spin polarization. These properties provides us multiple effective ways to detect and regulate the MZMs by using the chirality-induced spin selectivity (CISS) effect and the related spin-polarized currents in chiral materials.
