Eukaryotic cells comprise a plurality of organelles special via their particular membranes and contents. Their biogenesis happens by means of development and department of preexisting buildings instead of de novo. Mitochondria and chloroplasts, which seem to be descended from prokaryotic ancestors, have retained a few DNA and the biosynthetic power for its expression.

The photochemistry of enones depicted in Figure 4 for the a,&enones. The a+n* absorption for typical j,y-enones without conjugating substituents is centred at ca 220nm and the n + a * absorption typically has 1,, 290-3 10 nm. What is notable is the intensification of the n + a* absorption for many (but not all) B,y-enones, with values of ~ 3 - 1 0times as large as for a,Benones (see Table 2 for representative examples). This effect has received a great deal of attention from spectroscopists, and is discussed at length in a review by Houk6 on the spectroscopy and photochemistry of b, y-enones.
