  • The photochemical reaction mechanism has been investigated for methanol insertion into the p-substituted phenylketo carbenes. The triplet spin state of phenyl koto carbene is stabilized by the neighbored carbonyl electrons. When the phenylketo carbene reacts with methanol, the ylied intermediate is formed, then moves to the activated transition state.

  • In teleost, vitellogenin (Vtg) is synthesised in the liver in response to estrogens and transported by the blood to the growing oocytes where it is incorporated by micropincytosis (Selman and Wallace, 1982). Generally, Vtg is not induced in normal male fish but male fish are capable of synthesis Vtg in reponse to exogenous estrogen and xenoestrogens. (omitted)
