21. The first materials on which LON was demonstrated were dendritic macromolecules and carbonaceous films. 22. A polymer is a substance composed of macromolecules . 23. :: Well, you could use other methods to detect lithium in macromolecules . 24. Staudinger studied macromolecules and their chemical structure and collaborated with Hermann for many years. 25. The stereochemistry of macromolecules can be defined even more precisely with the introduction of triads. 26. Because of their size, macromolecules are not conveniently described in terms of stoichiometry alone. 27. High concentrations of macromolecules in a solution can alter the effective concentrations of these molecules. 28. The depression of metabolic rate during aestivation causes a reduction in macromolecule synthesis and degradation. 29. Macromolecules can sometimes be transported through transcytosis.30. Thus, macromolecules intended to be transported out of the nucleus will accumulate there instead.
