The enzymatic conversion of all trans β-carotene to retinal by an intestinal mucosal enzyme (β-carotene cleavage enzyme, BCC) from autopsy samples of human neonates was demonstrated for the first time. The enzymatic product was characterized as its O-ethyl oxime, which, on high pressure liquid...
The third-order nonlinear susceptibility of all-trans β-carotene dissolved in benzene or carbon tetrachloride has been measured by third-harmonic generation at several incident laser wavelengths from 1.030 to 1.221 μm. Its magnitude grows from 1.8×10 −11 esu at 1.030 μm to 3.8×10 −11...
