| Tartalmi kivonat: | The new experiments are the methodological continuation of the previously published ones.The length of time of the degradation with 2-aminoethanol was 4, 5 and 6 days, but the oxidation with KMn04 and the dissolution with merkaptoethanol remained of 24 hours. In this way the most moderate degradation in this new series was stronger than the strongest degradation of the previous series of experiment. The new LM, TEM and SEM data indicated also this strong degradation. The SEM results of the degradation with 2- aminoethanol and the oxydation with KMn04 resulted in superficial globular biopolymer units. The diameter of these units is 40-400 Â, much larger than that of discovered by the previous experiments. The TEM method indicated the degradation of the quasi-periodic and quasi-equivalent biopolymer structures. These new results confirmed, that for the biopolymer symmetry operations the experiments No. AKP-99-4,5,7,8 published in the previous publication are the most suitable. |
