The physicochemical properties of flax fiber cell wall rhamnogalacturonan I (RG-I) and its fragments, obtained after galactanase treatment (fraction G1), were characterized. RG-I retains its hydrodynamic volume after its molecular weight decreases by approximately half, as revealed by SEC. Two techniques, DLS and NMR, with different principles of diffusion(More)
Consecutive ring-expansion reactions of oxiranes with dimethylsulfxonium methylide were studied experimentally and modeled computationally at the density functional theory (DFT) and second-order Møller-Plesset (MP2) levels of theory utilizing a polarizable continuum model (PCM) to account for solvent effects. While the epoxide to oxetane ring expansion(More)
The article presents the structural principles of microwave-induced formation of new gel type from pectic rhamnogalacturonan I (RG-I). The backbone of gel-forming RG-I does not contain consecutive galacturonic residues and modifying groups that can be the cause of junction zone formation as it occurs in course of classical ways of pectin gelation. Microwave(More)

The article investigates the discursive manifestation of autobiographical memory, enabling to understand the social and communicative nature of this phenomenon. Autobiographical practices represent the social and cultural materialized form of the fixation of autobiographical memory determined by speech norms and memory mechanisms; autobiographical practices(More)
