Comparison of these curves with the absorption spectra of biological compounds shows that the efficiency curves resemble very closely the absorption spectra of certain sterols. The sterol curves which are very similar to the efficiency curves are for three vitamin D precursors, namely, 7-dehydrocholesterol, ergosterol, and lumisterol. In Figure 6, the photo- chemical efficiency curve for inhibition of closure of the neural tube for a distance of at least one-third its length when correction is made for absorption by the vitel-.
