    Notes: The synthesis and the properties of permutoids with ionic active groups and the kinetics of the decomposition of diazoacetic ester and of nitrosomethylurea through the ionic active groups are dealt with. A discussion follows of the synthesis of high polymers and permutoids with active groups of the chlorophyll and hemin series obtained by the introduction of the corresponding active groups into high-polymeric compounds, by copolymerization, and by inclusion of the prosthetic group in the polycondensation process. A report is added on the optical properties of the high-molecular compounds provided with active groups and on remarkable differences between low-molecular compounds in a dissolved state and as active groups linked to high polymers. The apparatuses developed for taking absorption and reflection spectra are described. Finally, the catalytic effect of the high polymers provided with active groups of the hemin series is examined.

    Notes: Syntheses of high polymers with active groups of the hemin and chlorophyll series and their optical properties, the shifts of the band maxima, and the change of the acid dissociation constants of the active groups are discussed. This touches upon the question of the existence of inclusion compounds in solution. The existence of true compounds in solution was proved by applying the law of mass action to several known inclusion systems. The acid dissociation constants of some dyes and their cyclodextrin inclusion compounds were determined by means of prototropy equilibria. The system serum albumin/methyl orange and macromolecular compounds with active groups of the hemin and chlorophyll series show a similarity to true inclusion compounds in solution, which suggests the existence of inclusion regions in the high polymers in question. Furthermore, syntheses of D-, L-, and DL-forms of polyphenylalanines substituted by active groups, their optical and catalytic properties, and first experiments regarding a synthesis of cytochrome c models are discussed.
