Once inside the cell, the sulfenate-linked, benzylcarbamate dimer, with two of vitaletheine's sulfenic acids encapsulated within its molecular matrix, can release the sulfenic acids (VSOH) when the calcium stabilizing the matrix is pumped offl. The benzyl groups probably help to get the complex through the cell membrane, like the classical Trojan horse, and are probably released as benzyl alcohol, which can be oxidized to benzoic acid, a common preservative and component of foods. The matrix of this complex is apparently extraordinarily stable, so far for decades, making this among the most interesting of molecules for immune support.
