Biological Chemistry of Organelle Formation

Eukaryotic cells comprise a plurality of organelles amazing by way of their particular membranes and contents. Their biogenesis happens by way 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.

Applying of results obtained to experimental data The direct comparison of results obtained with experimental data i s now unfortunately imnossible, because of the p r a c t i c a l absence of such experiments. However the suggested model and c a l c u l a t i o n method can be used f o r i n t e r p r e t a t i o n of some data obtained during the study of the s o l - f r a c t i o n properties i n the process of network formation. Irzhak, Enikolopyan et a l . [ 9 - l 0 l found the sharp decrease of i n t r i n s i c v i s c o s i t y of the s o l - f r a c t i o n with polymer concentration during crossl i n k i n g of p o l y v i n y l b u t y r a l containing some unreacted hydroxyl groups with diisocyanates /at constant M and the average cross-linkages number/.

In spite of the great importance of the study of regularities of cross-linking reactions, the experimental and theoretical analysis of such processes is complicated by many difficulties. Complexities of the experimental study are due to the difficulty of the isolation of the intramolecular reaction properly said, as even for the reaction in very dilute solution the probability of cross-linkage formation between different molecules is not negligible. Another difficulty: the measuring of the characteristic parameters of the reaction [kinetics, hydrodynamic properties].
