    "abstract": "We used computer simulation to calculate the electric dipole moments of the\nalpha and beta tubulin monomers and dimer and found those to be |palpha|=552D,\n|pbeta|=1193D and |palpha-beta|=1740D respectively. Independent surface plasmon\nresonance (SPR) and refractometry measurements of the high-frequency dielectric\nconstant and polarizability strongly corroborated our previous SPR-derived\nresults giving delta-n/delta-c ~1.800x10^-3 ml/mg. The refractive index of\ntubulin was measured to be n_tub ~2.90 and the high frequency tubulin\ndielectric constant kappa_tub ~8.41 while the high-frequency polarizability was\nfound to be alpha_tub ~ 2.1x10^-33 C m^2/V. Methods for the experimental\ndetermination of the low-frequency p are explored as well as ways to test the\noften conjectured quantum coherence and entanglement properties of tubulin.\nBiobits, bioqubits and other applications to bioelectronics are discussed.",
